Mind has light that blinks in my face on side of windshield. Most majority new carts has light in mirrors that blinks. Then, there 80% that don’t use them.
IMO bigger problem yielding before entering MMP small roundabout coming out or tunnel, If cart entering roundabout blinker on or off still have yield to your left. Maybe better idea would be automatic blinker lights turning on when turning and off when straighten back up? I also read somewhere we’re we are supposed to use hand signals when turning?
IMO the less splicing on harness the less chance for corrosion and problems.
