About The TIR LED Grille and Surface Mount Light - Undercover 12 FL

The Undercover 12 FL Grille and Surface Light is what you’re looking for if you’re a volunteer firefighter who doesn’t want the family vehicle to be all decked out in LED emergency lights. This small, unobtrusive surface or grille light can be mounted either inside or outside of your vehicle and is hardwired to its own switch. 19 flash patterns can be set to cycle, work side by side, move in and out, or can be synchronized or wired to alternate. Add 18 Watts of high-intensity illumination to your POV from Generation IV LED bulbs and you’ve got a phenomenal light system that can work for 100,000 hours, and it’s only 5.75” long and less than 2” tall. The light can be installed low, on running boards or push bumpers, because it is waterproof; the polycarbonate units are sealed with epoxy. The TIR lenses are strong, won’t scratch or shatter, and stay clear. Mount flanges are included, but L brackets (bought separately) can be used to secure the lights. A choice of bezels, either chrome or black, makes the lights go virtually unnoticed when mounted. You’ll have all the light you want to look ‘professional’ when called out to fight fires if you install the Undercover 12 Fls.
