Five years ago I bought and installed a 35 Watt kit from China bought on Ebay. No problems whatsoever on my 06 RT. Except my info display shows headlight out errors on one or both lights on startup but these go out in just a few seconds. Both lights work flawlessly. I paid $35.00 for the complete kit.
