If you notice he still has the turn signals on the bike.
I don't know if you could get away with just the ones on the grips?
Maybe one of our wonderful police officer forum members can answer that.
Would these pass for front signals?
I knew someone did.
I thought someone posted a link to some screw on signal caps. It appeared they worked with the stock or aftermarket grips. Just wire them in and replace the end caps.
At least I think that is what I saw.
If not. Someone better get on it cause that is a damn good idea.
