Turn Signal Dampers - Electrical Function?

Mounting new turn signal stalks on a 1980 KZ440B1. OEM stalks mount to chrome fork ears through two rubber grommets, and are grounded with a collar attached to the stalk on the inside of the ears. I think this is pretty common for a lot of period KZs. As I'm doing this, I wind up with a lot better fit for the aftermarket stalks if I do not use the rubber damping grommets. But it occurs to me that those grommets not only damp vibrations in the turn signal but also isolate it from the frame which would also ground the turn signal.

So here's the question: Do those damping grommets serve an electrical function such that if the turn signal contacts the metal fork ears the ground would be screwed up?

No they are vibration dampers. The turn signals ground through the ground terminal that goes under the mounting nut. The lights have to be grounded to work so isolating them would keep them from working.

If the rubber dampers are not used, I suspect vibration would kill the filaments in the bulbs pretty quickly.
