5100M 29" Linear LED Mini Light Bar

The 5100M 29" Linear LED Mini Light Bar is a larger magnetic rooftop warning light for buyers who want stronger vehicle presence, wider warning coverage, and a smoother linear-style output than many smaller compact mini bars can provide. With 56 Gen V 3-watt LEDs, 168 watts of total output, Linear 1 Optics, 36 flash patterns, Dual Memory, and full 360-degree warning visibility, this model is made for work vehicles that need more than a basic compact strobe bar.

At 29.5 inches long, 12 inches deep, 3.375 inches high, and 16 lbs, the 5100M gives larger pickups, tow trucks, utility trucks, construction vehicles, service trucks, work vans, and municipal support vehicles a stronger rooftop warning signature without moving into a full-size light bar. It is still low profile for a 29-inch rooftop unit, but it has enough size and weight to feel like a serious piece of warning equipment once it is on the vehicle.

The biggest reason to choose the 5100M is its Linear 1 Optics. This optic style has been part of ETD’s warning-light lineup for years because it creates a broad, clean, highly visible warning spread around the vehicle. Buyers who want a wider visual footprint, strong 360-degree awareness, and a more substantial warning presence than a short mini light bar should have this model on their list.

For buyers comparing size, mount type, and output across similar rooftop options, the 5100M fits naturally inside the Mini LED Light Bars lineup.

Larger Mini Bar Presence Without Going Full-Size

The 5100M is for buyers who want more rooftop visibility than a short compact bar can realistically provide. Its 29.5-inch length gives larger vehicles a stronger visual footprint, while the 3.375-inch height keeps the setup low enough to avoid the bulky look of many taller warning bars.

This makes it a strong choice for tow trucks, wreckers, service trucks, utility trucks, construction pickups, municipal vehicles, and work vans where a 12-inch or 17-inch mini light bar may look undersized.

56 Gen V 3-Watt LEDs With 168 Watts of Output

The upgraded 5100M now uses 56 Gen V 3-watt LEDs for 168 watts of total output. The new LED package gives this bar the output buyers expect from a larger 29-inch rooftop warning light.

For daytime roadside work, jobsite caution, tow recovery, utility service, construction traffic, and fleet warning use, that stronger LED platform helps the 5100M feel like a real professional upgrade instead of another basic magnetic mini bar.

Linear 1 Optics for a Wide Warning Spread

Linear 1 Optics are one of the defining features of the 5100M. Linear 1 Optics help create a broader, smoother warning spread around the vehicle, which supports stronger 360-degree recognition from multiple viewing angles.

That makes this model a smart choice for buyers who want a fuller rooftop warning signature rather than a smaller, tighter optic pattern. It also helps separate the 5100M from lower-cost compact bars that may flash brightly up close but do not create the same professional vehicle-wide presence.

36 Flash Patterns With Dual Memory

The upgraded 5100M includes 36 flash patterns, Dual Memory, and non-volatile last-pattern recall. That gives users more flexibility than the older 26-pattern setup and makes the light easier to use in repeat applications.

Dual Memory lets the operator save two preferred flash patterns and switch between them faster. Non-volatile memory recalls the last pattern used when the bar powers back on. For tow operators, utility crews, construction vehicles, and support fleets, that means less time cycling through modes and more consistent operation from one use to the next.

Plug-In Convenience With Hardwire Flexibility

The included 12V cigarette lighter plug gives the 5100M an easy plug-and-play starting point. The upgraded plug includes ON/OFF, flash-pattern, and Dual Memory switch controls, so the operator can manage the bar from inside the cab without adding a separate control box.

For buyers who want a cleaner permanent setup, the 5100M can also be hardwired. That gives the bar more long-term flexibility than a plug-only magnetic warning light.

Built for Real Work-Vehicle Use

The 5100M combines an extruded aluminum housing, polycarbonate Linear 1 lens, IP67 weather rating, 160 lbs of magnetic holding strength. That combination gives buyers a stronger ownership story than cheaper mini light bars that focus only on price.

It is especially useful for larger vehicles that need warning visibility in active traffic, bad weather, jobsite conditions, or roadside work environments where the light has to be seen from more than one direction.

A Strong Linear-Output Alternative in the Mini Bar Lineup

Not every buyer wants the smallest bar, and not every buyer wants a full-size rooftop light bar. The 5100M fills the space between those choices. It gives buyers a larger mini light bar with strong output, 360-degree visibility, linear optics, magnetic convenience, and a hard-mount option for more committed installs.

Buyers still comparing size, optics, and mount type can use the Mini Light Bars Buyer’s Guide to decide whether the 5100M is the right fit.

Magnetic Mounting for Fast Rooftop Setup

The 5100M includes magnetic mounting for buyers who want fast rooftop placement without starting with a drilled installation. This is useful for work vehicles, service trucks, utility vehicles, tow units, and temporary-use applications where flexibility matters.

The bar uses 4 magnets rated at 40 lbs each, giving it 160 lbs of total magnetic holding strength.

Magnetic Mount Use Guidance

The magnetic mount should be used on a clean, dry, compatible steel surface. The roof and magnet contact areas should be free of dirt, grit, dust, and debris before placement. This helps the magnets seat more consistently and reduces the chance of trapped material affecting the vehicle finish.

Because this is a larger 29-inch bar, buyers should treat mounting surface prep seriously. Roof shape, paint condition, steel compatibility, cable routing, and magnet contact all matter.

Higher-Speed and Daily-Use Recommendation

For regular higher-speed driving, daily fleet use, or full-time vehicle installation, the optional hard-mount kit is the better path. The magnetic setup is practical for removable rooftop deployment, but a hard-mounted installation provides stronger long-term confidence for vehicles that will keep the 5100M installed as part of their regular equipment.

Low-Profile Rooftop Fit

At 3.375 inches high, the 5100M keeps a lower rooftop profile than many buyers may expect from a 29.5-inch warning bar. That helps it fit work trucks, utility vehicles, service vans, and tow units without looking overly tall or awkward.

Before ordering, buyers should still check available roof space, cable routing, antennas, roof racks, garage clearance, and any other equipment already mounted on the vehicle.

The 5100M includes 36 flash patterns to support a wide range of warning needs across tow, recovery, utility, construction, roadside, municipal, and general fleet applications. That gives the operator more flexibility than the older 26-pattern setup and makes the bar easier to match to different warning environments.

Dual Memory is one of the most useful upgrades on this model. It allows two preferred patterns to be saved, which helps users switch faster between common operating modes. A tow operator, for example, may prefer one pattern for general roadside presence and another for more active recovery scenes. A utility crew may prefer one mode for moving work and another for stationary jobsite caution.

The non-volatile memory function recalls the last flash pattern used when the light powers back on. That improves repeat-use convenience because the operator does not have to start from the beginning every time the vehicle or light is restarted.

The upgraded cigarette lighter plug includes ON/OFF, flash-pattern, and Dual Memory switch controls. This keeps operation simple for buyers who want in-cab control without a complicated install. The bar can also be hardwired for a cleaner or more permanent setup.

The 5100M is built for full 360-degree rooftop warning visibility. Buyers who need directional lane guidance or scene illumination should compare other product types.

The 5100M is a strong fit for:

• Pickup trucks
• Tow trucks
• Wreckers
• Roadside assistance vehicles
• Service trucks
• Utility trucks
• Construction vehicles
• Work vans
• Municipal support vehicles
• Commercial fleet vehicles
• Contractor vehicles
• Larger support and response platforms

It is especially well suited for:

• Tow and recovery operators
• Wrecker crews
• Roadside service teams
• Utility and service technicians
• Construction fleets
• Municipal and public-works vehicles
• Contractors
• Fleet buyers
• Work-truck operators
• Responder-adjacent support vehicles where lawful

This model makes the most sense when the buyer wants a larger rooftop warning signature than smaller mini bars can provide. On a full-size pickup, tow truck, utility vehicle, or service van, a short mini bar can sometimes look visually underpowered even if it flashes brightly. The 5100M solves that problem with more width, more roof presence, 168 watts of output, and Linear 1 Optics that help spread warning visibility around the vehicle.

For tow and roadside users, the 5100M gives the vehicle a more obvious external warning presence than interior lights alone. Buyers outfitting wreckers, rollback support vehicles, service pickups, or roadside assistance units can also compare broader options in the Tow Truck Lights category.

Compared with dash, visor, or hideaway lights, the 5100M provides roof-level 360-degree visibility from a single external unit. Compared with smaller mini bars, it provides more visual authority for larger vehicles. Compared with a full-size bar, it keeps a more compact footprint and simpler installation path.

This model is not the best choice for very small rooflines, compact cars with limited mounting space, or buyers who only need a lightweight temporary warning light. It is also not the right product for buyers who need traffic-advisor directionals, takedown lights, alley lights, or dedicated scene lighting.

The 5100M is available in 13 total standard color configurations, giving buyers strong flexibility across tow, construction, utility, municipal, fleet, roadside, and responder-adjacent warning applications.

Available standard configurations include:

• White / White
• Red / Red
• Red / White
• Blue / Blue
• Blue / White
• Red / Blue
• Amber / Amber
• Amber / White
• Green / Green
• Green / Amber
• Blue / Amber
• Red / Amber
• Green / White

Amber / Amber and Amber / White are strong choices for tow trucks, construction vehicles, utility trucks, roadside service, municipal work, and contractor vehicles where caution visibility is the main goal.

Blue-based and red-based configurations may be appropriate for authorized emergency, volunteer, or responder-style applications where legally permitted. Green can be useful for certain command, security, utility, or specialty applications depending on local rules and agency policy.

The right color depends on vehicle role, state law, local regulation, department policy, and intended use. Buyers should always confirm that the selected color is legal for their vehicle and application before operating the light on public roads.

How bright is the upgraded 5100M?

The upgraded 5100M uses 56 Gen V 3-watt LEDs for 168 watts of total output. That gives it significantly stronger product-page positioning than the older 56-watt version and makes it a better fit for larger work vehicles that need serious rooftop warning visibility.

What changed from the older 5100M version?

The current upgraded version has Gen V 3-watt LEDs, 168 watts of total output, 36 flash patterns, Dual Memory, non-volatile last-pattern recall, a 10 ft 8 in cord, and updated product specs.

What are Linear 1 Optics?

Linear 1 Optics are ETD’s established linear lens style used to create a broader, smoother warning spread around the vehicle. On the 5100M, they help support full 360-degree rooftop visibility and give the light a wider warning presence than many smaller compact bars.

Is the 5100M good for tow trucks and roadside vehicles?

Yes. The 5100M is a strong fit for tow trucks, wreckers, roadside assistance vehicles, utility trucks, and service vehicles that need a larger rooftop warning presence with full 360-degree visibility.

Is this light bar low profile?

Yes. For a 29.5-inch rooftop mini light bar, the 5100M has a low-profile 3.375-inch height. It still gives the vehicle a serious warning presence, but it avoids the taller, bulkier profile of some larger rooftop warning bars.

Does the 5100M have Dual Memory?

Yes. The upgraded controller includes Dual Memory, allowing two preferred patterns to be saved. It also has non-volatile last-pattern recall, so the bar can return to the previous pattern when powered back on.

How many flash patterns does the 5100M have?

The upgraded 5100M includes 36 flash patterns. This replaces the older 26-pattern spec and gives operators more flexibility for roadside, construction, utility, tow, and fleet warning use.

Can the 5100M be hardwired?

Yes. The 5100M includes a 12V cigarette lighter plug for immediate use, but it can also be hardwired for buyers who want cleaner cable routing or a more permanent installation.

Does the magnetic mount hold securely?

The 5100M uses 4 magnets rated at 40 lbs each, for 160 lbs of total holding strength. Proper placement on a clean, compatible steel surface is still important for best performance.

Will the magnets scratch my roof?

Keeping the roof and magnet contact areas clean helps reduce the chance of grit or debris affecting the finish. The surface should be clean, dry, and compatible before mounting any magnetic rooftop light.

Is the 5100M a traffic advisor?

No. The 5100M is a 360-degree warning light bar, not a dedicated traffic advisor. Buyers who need directional lane guidance should look at a traffic advisor or directional warning product.

Who should choose the 5100M instead of a smaller mini light bar?

Choose the 5100M if you have a larger pickup, tow truck, utility truck, service vehicle, work van, municipal support vehicle, or contractor fleet vehicle and want more rooftop presence than a shorter mini bar can provide.

Who should not choose the 5100M?

This is not the best fit for very small rooflines, compact vehicles with limited mounting space, or buyers who only need a small lightweight removable warning light. It is also not the right model if you need takedown lights, alley lights, traffic-advisor functions, or scene lighting.
