I can't find the actual units i got ( Was 3 years ago) but i purchased them from Alchemy parts motorbike accessory on line.. LED projector lens stop and tail lights.... I did try the hollow bolt idea but couldn't' get the wire through without making the bolt to thin and weak, don't forget it has to handle vibration! the rear lamps still look exactly as they did standard.... sorry can't take the lens off to show because they are permanently glued now!
