About this kit

40-Inch Quad Row LED Light Kit, fitment-checked

Rough Country 70847 is a 40-inch quad row LED light kit for the 2014-2021 Toyota Tundra, sold with the vehicle-specific hood bulge mount that positions the bar over the hood vent. Four rows carry 96 LEDs each for 384 total, with an IP68 waterproof rating. Off-road use only, and the harness must be spliced into the vehicle's wiring during installation.

This 40-inch quad row LED light kit for the 2014-2021 Toyota Tundra fits 4WD and RWD trucks across SR, SR5, Limited, Platinum, 1794 Edition, Nightshade, TRD Pro, and Trail trims. The kit pairs the light bar with a matched hood bulge mount that locates the bar on the factory hood vent using automotive-grade 3M adhesive pads, so no bracket fabrication is needed. Plan on a splice into the truck's wiring for power, and treat the bar as off-road lighting only. Rough Country lists an install time of 3-4 hours, and a downloadable installation guide is available.
