Hi guys, I have a 2010 Prius with the parking light on the passenger side not working (this is the little bulb that goes on top of the low beans). The other side works fine no problem, swapped the bulbs and nothing. Could it be the fuse? Tested with regular bulbs and a set of new LED error free bulbs with the same result.
idk if there is a fuse for each side. check the voltage, maybe a wiring issue, connector corrosion, etc.
Connectors would be my first suspect. Wires fail, not nearly as often and only if provoked. Fuses generally have to be provoked.
