I am updating a 2015 Yamha gas cart. It's a great cart with about 150 hours.
I'm thinking of adding a speedometer, adding retractable seatbelts, replacing the original headlights with LED lights, and adding a USB port.

Can you guys tell me whether these are good updates? Also what they cost if you've had it done. I also wondered which speedometer is best for puttering around in the Villages. Any other comments or suggestions are appreciated.

Thanks.
