How to install 9005 bulbs in place of 9145 bulbs

It’s important to know the differences between these 2 headlight bulbs because they are very similar. The wiring also looks the same, but it’s not, therefore you need to be able to identify and modify each one to achieve your goals:

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.

The original 9007 halogen bulb is held in place by a retainer. In the case of this Ford F250, the retainer is very tall. Sometimes they are snort and sometimes they are tall, but they all work the same way. The retainer goes on top of the bulb and holds it in place. Here you can see how the original halogen bulb sits when you take the retainer off. The new GTR Lighting GEN 2 LED Headlight Bulb is a little longer than the original halogen bulb, but it doesn’t matter for this application because there is nothing inside the housing to interfere with it. The mounting method is identical. The new LED bulb has the same mounting collar as the halogen bulb. Here’s an aerial view showing the slots in the mounting collar between the original halogen bulb and the new GTR Lighting LED headlight bulb. They insert into the headlight housing the exact same way as each other. The housing for either a 9004 or a 9007 will have 3 alignment tabs inside like this. The bulb will only seat one way. This is how the new 9007 LED headlight bulb should seat when you have it resting on the housing. There should be no gaps, it installs perfectly flat. The original retainer that held the halogen bulb in place will likely NOT fit over the top of your new LED headlight bulbs, they are far too large to facilitate the heat sink and cooling fan. The mounting collar on the LED headlight bulbs comes off easily by twisting it. Separate all the parts and re-install the original headlight bulb retainer between the heat sink of the LED bulb, and the mounting collar.
