Washed my bike today (had so many bugs on the front that I think it made the front end heavier LOL) and as I was finishing up I was looking at the stock turning signal, wondering if it is reflective on the inside at all... So I took the amber plastic off just to find out that it is not really reflective. The inside is black plastic with a quick (and incomplete) spray of silver-ish color. Had some 3M reflective tape lying around and I put two pieces behind bulbs on both sides on the back and you know what - I swear it is noticeably brighter when looking from the back? Plan on doing the front too, and need to check the brake light too - not sure what kind of reflector is in there... There you go... a quick cheap mod, every bit helps I guess!
