How to install 9004 or 9007 LED Headlight bulbs from GTR Lighting
OK, so I got my hands on a set of the 9007 LED headlight bulbs from GTR Lighting and I wanted to show you how to install them because at first glance it looks kind of tricky.
The vehicle I’m going to demonstrate on is a headlight from a 2002 Ford F250. This is a very common headlight and I will tell you this: These headlights suck!!! No matter which types of bulbs you use, high power halogen, HID or new LED style headlight bulbs, these housings are awful and it’s impossible to get amazing light output from them. Your best bet for amazing light is a light bar or a projector retrofit… but that’s a whole other story! For now we’re going to try to put these GEN 2 9007 LED Headlight Bulbs from GTR Lighting into these housings.
Here are a couple notes about the final install:
If you have a tall mounting adapter like shown in these pictures, it may be a good idea to either drill holes in it to allow the LED bulb fan to “breathe” and flow more air to keep it cool, or just trim the excess material off to allow the LED heat sink fan/bulb to be fully exposed.
In order to get the LED bulb and mounting adapter fitted to the housing there are several things to line up and it can be a tricky puzzle! Just examine it and see how everything fits together. The housing has alignment posts, the LED bulb collar has 2 alignment posts, and the mounting adapter for the original bulb has 2 sets of alignment posts!!! Everything has to be put together just right.
This install guide is specific to the early 2000’s Ford trucks that use 9007 or 9004 headlights, but the basic premise should be universal to anyone trying to install 9004 or 9007 LED headlight bulbs.
