Instead of creating a new thread I'm going to add to this older existing thread.
After 75k both of my license plate bulbs have finally burned out. Thought I would post some pictures of the change out process since I didn't see any in the existing threads. I accessed the bulbs by removing the trunk liner. The entire process took maybe 20 minutes.
I mistakenly installed 194 type bulbs instead of 168. While identical in appearance, the 194 has a lower lumen output but a higher rated life than the 168. I wanted to go LED, but couldn't justify $10 per bulb + shipping.
Hope the pics help for anyone wanting to change out bulbs.
