Hi, i'm new here but I've read some of the posts. Anyway, my wife's 95 ES300 has one of the rear brake lights out. I was going to change it but when I took a look to replace the bulb, I couldn't see any sockets. Do you have to remove the whole tail light assembly just to replace a bulb? Also what size nuts are used (8mm, 10mm?). Any help is greatly appreciated.
