I did a tail tidy last year and had to install an aftermarket light for the lisence plate. It works well, but it's a blue-ish light and it kind of clashes with the age of the bike.
I thought about this and I started looking for compatible headlights. My buddy had a gs500 from the same era (1993 I believe) and his tail light has an integrated lisence light (clear plastic under the tail light section that illuminates using the DRLs.
Looking on ebay, it seems that they both mount on the same tabs and are of similar shapes.
I'm thinking about picking one up to try, have any of you guys tried this before ?
