Tail Light Bulbs
LED Tail Light Bulbs: Find the Right One Fast
Your tail lights look duller than the truck next to you at the light, or your turn signal is blinking too fast since you swapped a bulb. Before you buy anything, figure out which function is actually failing: brake, reverse, turn signal, or license plate, because each one uses a different bulb base and sometimes different wiring. Get that right and the rest of the install is plug and play.
When we tested reverse light bulbs, the GTR Lighting Ultra series measured 1,200 lumens per bulb, which is right in line with a stock halogen headlight bulb, so a reverse bulb swap alone can throw as much light backward as a headlight throws forward.
On brake and turn signal bulbs, color match beats raw output every time: a red LED behind a red lens will outperform a brighter white LED behind that same lens, because the lens filters out everything except red wavelengths and the white bulb ends up looking dim, or worse, pink.
Every bulb here is HR Tested for fit and function in our own shop before we list it.
Pick your bulb by the job it needs to do
For a hard, urgent stop signal, this is where you land red LED bulbs like the GTR Lighting Armor series, built to punch through a red lens instead of fading into a dull pink glow.
Backing up in the dark gets fixed here, with white LED reverse bulbs such as the GTR Lighting Ultra series pushing near-headlight brightness straight out the back of your truck.
If your blinker hyper-flashes or throws a dash error after an LED swap, this is the lane for amber bulbs like the GTR Lighting Carbide series, built to skip resistor wiring entirely.
Small housing, easy fix: this covers the mini wedge and festoon style LED bulbs that light your plate without cooking the little plastic lens sitting above it.
Not sure which function you need yet? This is the full bulb lineup across every socket style and color so you can cross-reference by shape instead of function.
