Maybe I'm paraniod, but I like to be as safe as I can on my bike. I like to be seen by other drivers.
Besides my turn signal modification I added a LED tail/stop light.
Tail lights and LED on.
I made a backing plate out of aluminum sheeting.
Backing plate and wiring route.
Ground wire and power lead routing.
Wires routed through tail light hole.
LED power leads connected inside tail light housing.
