I've been doing alot of research on converting my (wife's) SRT6 roadster to LED lighting. I found these great high power
ERROR FREE (meaninig the bulb has a built in load resistor so it won't trigger the bulb out warning light) LED projector style back up light bulbs. They are NOT cheap but they seem to be perfect for replacing the back up light bulbs. Thought I would share . . .
Here's the link on where I found these (where to purchase) . . .
