I installed these bulbs in my 2010 cc last night. I have tinted windows to the legal tint in NC which is 35%. No tinted tail lights. No back up camera. I do have the racing dash LED license plate lamps from ECS. (and I highly recommend them) but as for the the led reverse lights.... Yea they look cool but as for help with backing up... It isnt better at all maybe even worse. Most of my back up light comes from the tag lights.
