I picked up my ridgeline a couple months ago and love it so far. On my past few vehicles I have done HID retro-fits and wanted to do the same on the ridgeline.
here are some pics of the retro-fit.
projectors used are bosche bi-xenon
ballasts are morimoto 35 watt
bulbs are d2s osram cbi's.
the projectors
baked the lights in the oven for 3 minutes at 350 degrees. they came apart real easy. I dont recall where I got the projectors. may have been ebay. there the same ones that come on alot of mercedes.
no certain size. I used 3" projectors. I used these projectors to because I had used the same kind on a truck retro I did and there suited well for a truck/suv application.
Hey HIDridgeline where can I find the same set up you used for your ridge? I've been looking online to see what's a good conversion kit and I can't find anything I'm comfortable installing in my truck.
you wont find the set up I have. you have to make it yourself. I used e-46 bosch bi-xenon projectors, e46 extended shrouds. morimoto 3five ballasts and osram cbi d2s bulbs. then cut the reflector in the oem headlights to mount the projectors to. I got most of the parts from theretrofitsource.com the projectors came from ebay.
I used acura TL projectors in my wifes nitro. they are amazing. I am working on doing a different retro fit for my ridgeline using nissan murano projectors.
here is a shot of there out put.
