i want to retrofit my headlights with projectors, but i already have a HID kit. anyone know what lens' has a H11 input, so i don't have to get a new kit?

Honestly, I dont know of any, but even if there were, i doubt they would meet the size requirements you need for that setup. I think you are going to have to get new bulbs at least. Depending on the projectors you end up with, you should just be able to snag a set of bulbs, and be fine. You will need an adapter if you end up going with a D2S setup.
