How do I change out the driver side rear marker light

 

The ones on the side are LED. Take the two screws out, unplug it, plug the replacement in, put the two screws in.

They CAN be repaired. It requires getting the correct 4 pin LED diodes, cutting the back of the light open with a dremel, carefully desolder the dead LED diodes and solder in new ones, silicone the back on and let that cure and reinstall it.

I'm not sure new ones are available anymore. Used ones are not very cheap either.... Part of owning an H2.

 

new ones are available but they are 210.00 is what I was quoted. I found one on Ebay for 60.00 from a salvage yard.
