I have had the best luck with RETRO. I tried Phillipd HID's and they worked just the oppisite. High beams were low and vise versa. Stick with Retro in my oppinion.
New guy from Durango Colorado. I saw this site mentioned a couple times on the Nation and thought I would try this one out. I own a 08 F250 ccsb with intake, exhaust and a Mini max. Pictures will be posted soon. Jake
