I decided originally to replace the
indicators that came with the bike (aftermarket) as they neither matched or
looked any good.
I went with a set of carbon arrow clear lenses (amber bulb) aftermarket indicators which did look ok.
The downside to these indicators were when the wind hit them it broke the rubber and thus caused them to flop.
I decided to replace them with Gregg's flush mounts which are much better (indicators current).
