Is there any way to convert h3 to h4 bulbs? i want to buy projectors for my hids and wanted to know if its possible. Or would i have to buy another set of headlights

 

i dont think it would fit, h4 bulbs are bigger than h3 bulbs and projectors can not take those bigger bulbs or the bulb will be hitting the projector lens. you can sell the H4 HID's you got and get the new HID's for your projector. that's what i did. lol

i don't think the projectors takes the H3 i think it takes H1. not exactly sure though, that's what i always though
