I've been receiving some questions/compliments on my retrofit on here as well as some other forums so I thought I'd start a thread with some pics and info so people have a better idea of what the project entails. I don't have a how-to specific for the the X but I'll post the resources I used and hopefully in the future someone can do a write up.

Here is a link on theretrofitsource.com that will answer any questions about the benefits of projectors or almost any other question you would have: http://www.theretrofitsource.com/trs_tech.php I used a how-to I found on their website for the Morimoto Mini projectors that was helpful and covered all the steps other than a few modifications that are vehicle specific: http://www.theretrofitsource.com/pdf/trs_tech/Morimoto_Mini_H1_Retrofit.pdf Here are a couple pics of my X, Il try and get some better pics when I am home from school this weekend: After I painted the shrouds and housings: Installed without the lenses: On the vehicle: I went with 5000K bulbs that are pure white: The light output is incredible with a smooth cutoff and no glare to oncoming traffic: I know RacerXXL has done this mod so chime in if I missed anything and if you have any other questions just ask or send me a PM. I hope this helps out!
