I also had these same worries. I have read a few threads here where folks did in fact have some issues, and others that had none what so ever. But the weakness of the Factory Halogens was to great for me to ignore. Being in the North West makes for pretty short daylight hours during the winter months. I go to work in the dark and come home in the dark.
I called a lot of our vendors looking for an HID kit for the RT's.. With no luck. After a bit of research I found out why...
The solution is different for the RS than it is for the RT. We have the RT. Both the Fog and Headlights are sealed units. However, I learned form a vendor we can go to our kitchen ovens, set the heat to 200f, and it allows the sealant to become softened and we can separate them. Evidently it takes 300f+ before the actual plastic of the housing having any ill effects.
Then once we swap the bulbs out, we go back to the oven to soften the seal again. And "Clam" them back together.
Anyway, For all of my Autos I purchase all of my HID kits from Retro Solutions (
Link) They have helped me with any questions, been honest, and actually do warranty their parts.
That said, I learned about an HID installation from a fellow member InspectorGadget. He used
this Ebay vendor with a lot of success for his RT. The SLIM HID KIT CONVERSION LIGHT MOTORCYCLE H7/H4/H9/H3/H1. The headlights are the 9005(HB3) and the fog lights are the H8.
Now I did the installations on both my wife's 2007 Mustang GT on the Fog and Headlights, and on my Fog so far on my 2010 F150. The quality of the actual products was what I expected for the $$ I paid in regards to the Retro Solutions kits.
However the Ebay vendor product quality was equal to the Retro quality and that surprised me. I have purchased from a handful of Ebay vendors for HIDs and always was disappointed. This is the first time ever I was not.
I have not yet installed the HID kit on our RT because we have traded it in for a 2011 and expect delivery of that new bike in late November or Dec and will install the HID kit then.
To read up on InspectorGadget's thread (
Link) it is on a different forum, but worth the read if you plan to do it on your own.
