FWIW, I had an issue with the LED inserts for the taillights - one side worked and the other side failed within five minutes of installation. Tested them on a battery and it was definitely the unit. Snyders was great about shipping me a replacement immediately and giving me a return shipment label. But as the LED units are at their core electronic devices, infant mortality is a real issue. Best way to isolate where the problem is is to start with a direct hookup between the wires and a battery, then gradually add in elements until you find the failure point.
