I just put these in the rear turn signals:
1156-A45-T 1156 Amber

I had to file one on the the little bumps on the led bulb down as the didn't match original. It only took 1 min to file off and still "plugged" in fine.
I would say they are only about 20% brighter than stock. I'm happy I got them as I have the Brake Light Flasher the I rigged so my indicators strobe at the same time! I'll post a video of this - looks crazy!
