About The Undercover 4 TIR LED Grille and Surface Mount Lights

The Undercover 4 is our best-selling light, equipped with 4 Generation IV 3-Watt LEDs equaling 12 Watts of intense light output. It is one of our best selling online products because of its luminous power for its size and for its versatile interior or exterior placement options.

At just 5” long, this light is easily hidden just about anywhere on your vehicle; undercover and out of sight especially when you choose either the black or chrome bezel that matches the mounting surface. Yet with a flip of the switch, the 4 Generation IV 3-Watt bulbs with 19 strobe patterns kick ‘the 8’ into a super bright and highly visible power source in all weather conditions. With TIR, polycarbonate, weather resistant lenses that cut through dense fog or heavy rain, you never have to worry about being seen, and the ‘8’s’ are brilliant during daytime use as well! The Undercover 4 is also now available in Linear 1 Optics which gives our customers a great choice: a more focused beam with TIR, or a wider light span with the Linears.

I put this item on my vehicle as an exterior license plate unit and love it. It is super bright even in the day. And it cost less than half of a two head single color unit. I highly recomend it.

Very good product for the price. These are easy to install and very bright. If they are split color (Red/White) the rapid strobe patterns can blend the colors to bright pink, but with many patterns to choose from the problem can easily be resolved.

I ordered the split R/B and i must say, i really did not expect them to be as bright as they are, i have a set of whelen LINZ 6 grille lights that are similar, but the undercover 8 just blows the whelens out of the water. these are some truly amazing lights for the price.

Rated by raul

Beyond bright. Used them for doing military escorts and they are brighter than most full size light bars. I was asked by Highway Patrol following us if we could turn them down or off because they were too bright. Good luck finding that anywhere else, especially for the amazing price. Will be buying more lights soon.
