Took me a couple hours to do, the worst bit was trying to take the front lenses off of the lights, but once its done everything else is simple..

I have found that after doing this mod and going for a drive that the indicators are flashing very fast when on.. any idea on what could cause this or how it can be fixed... All the globes are working.
