so im ebay, trying to find projector headlights, and i was wondering what headlight would i use that also uses the 9004 bulb? and another thing, is there a certain size of a projector im supposed to use? i dont need a 500 mercedes or bmw projector, thats quite alright. if theres other out there, let me know.

 

I think you're mistaken. Once you replace your old headlights w/ projectors, that's it. You have projectors, nothing to do with 9004. You can potentially re-use some of the headlight harness to wire your new projectors, but that's about it.

 

Tatanko has pretty much covered the bulb issue, now if you decide that you want to put in projectors, it behooves you to put in bi-xenons so you can retain your high beams. Hella makes the Benz projectors...just do some research...if you're gonna do it...do it right IMHO
