Just bought a couple of these. Gonna install one on the 'F'

Could be an issue with Mr Plod, they don't like red or blue lights that strobe.

You may be right...but I'll take the chance. I saw one on a jap bike once...and it really does catch your eye.

Installed the flaser. Also installed a switch under the seat to change modes if I want.
Works great.
Pic's coming tomorrow
