I have a 2008 GTC and I have been looking for a thread showing or discussing the replacement of the incandescent license plate lights, interior lights, and side markers for LEDs, and have not been able to find one here, or anything in YouTube. Yes, I could pry off the bulb holders and look for Canbus LEDs replacements, but I am concerned with breaking or marring the wood veneers, particularly with respect to courtesy lights. I changed the bulbs at the outside mirrors using the thread in this forum and they work perfectly, and the step by step instructions were invaluable. Any suggestions will be appreciated. Thks.
