About The TIR LED Grille and Surface Mount Lights - Undercover 4 FL

The Undercover 4 is our best-selling surface mount fire light because it is equipped with 4 Generation IV 3-Watt LEDs equaling 12 Watts of intense light output. The 5” Undercover 4 FL has luminous power for its size, is mounted on the interior or exterior of your POV or auxiliary fire vehicle and is easily hidden just about anywhere on the surface. The light goes ‘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 high-intensity LEDs with 19 strobe patterns kick ‘the 8 FL’ into a super bright and highly visible power light source in all weather conditions. No one will know that you are using your own vehicle for emergency volunteer work until YOU hit the switch! With TIR, polycarbonate, weather resistant lenses that cut through dense fog or heavy rain, you never have to worry about being seen when doing your roadside duties. The ‘8 FL’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.
