My bike has an aftermarket part which permits the rear turn signals to also serve as running lights. The right signal/running light just began burning very dim, and the turn signal, when activated, flashes fast. Additionally, when activated, the right turn signal indicator flashed normally for the first three blinks, then blinks very fast. I have changed the bulb, but the problem still exists. Front signal seems to function properly as does both left signals/running light. Does anybody have any ideas as to what the problem might be?
