What are retroheadlights?
Is that a brand, or a company who built some custom lights?
You can only fit h1 bulbs you say.... gotcha,
"what will i all new"....what?
Ive not built any lights for a few years, but i did at 1 point use theretrofitsource.com supplies to retrofit a set of fxr projectors into stock housings. Clear up a couple questions for me/us and provide pics maybe?
