Getting HID's in my '12 Altitiude Pkg Laredo has been something I've been interested in since before I even placed the order for it. I looked at buying the factory units and having the dealer retrofit them as well as a few other HID kit options.
After reading billybrun's HID DIY thread a few times HID projectors headlamp retrofit - DIY (picture heavy)
and exploring various other threads here, I finally decided to make a phone call or two and get some parts ordered.
The second call I made turned out to be the only call I should have made, and that was to http://www.theretrofitsource.com
I spoke to Nate TRFS and he was exceptionally helpful and knowledgeable... not to mention a super nice guy. Unlike some of the other HID kit vendors TRFS had everything I needed. Two things were very important to me, one being projector housings as I have no interest in running HID's without projectors, and the other were plug & play harnesses that don't require splicing of the factory harness or extra wiring.
Nate helped me figure out exactly what I wanted, understood why I wanted it, was very honest in his opinions, and didn't try to sell me something I didn't need.
Now I realize I don't have any parts in my hand yet, but so far I'm very pleased and have that warm & fuzzy feeling with TRFS that one always hopes for with a vendor.
I'm expecting the parts sometime next week and will update.
