srs244 - I wrote to "Super Bright LED's" and specifically to a "Wade Fox" in the tech department about the can-bus bulbs. He said that the bulb's for the Crossfire are can-bus and that the correct number's are 1157-CW30-CBT for the brake light and BAU15S-A30-CBT for the turn signal. I've not tried these so I don't know if they accomplish what your looking for or not. If you look up SuperbrightLEDs.com you will find their contact information and you can call them for direct information. Hope this helps. Let me know what you find out and if you try them, how they work out.
