I ordered up a set of the round brake lights for my 88 911. Arrived today and installed. If this install takes more than 25 minutes you're drinking a lot of beer and that's okay.
I also threw on some brighter LED reverse lights I found online.
Needless to say, I'm VERY happy with these. I feel like everyone else around Scottsdale, AZ is used to the brand new cars ultra bright brake lights and giant cars so I wanted to do anything I could to help be seen in my daily driver!
Install
Running lights. LED on left, original on right, of course.
Brake light actuated. It's immensely brighter to the eye, but the camera only captured it a little.
Reverse Light difference. WOH! It's huge.

Then I put these in the interior. They are bright, but I prefer the yellow "natural" looking light more than the bright white. It almost hurts my eyes, but for now I'm going to leave it.
