Not sure if anyone has done this before or if im re-posting, but i did it yesterday and pleased with outcome so thought i would share.
i've removed the red filter in the rear lights and replaced with a CREE red LED canbus bulb, actually much brighter than a standard bulb behind the red filter and it looks a lot sleeker IMO.
its a bit of a fiddle to get it out but can be done without smashing anything and can be put back in if mind changed.
