Bike is mostly stock, 4800 miles. No idea how long they haven't been working. Changed the bars to Renthals before trip to WSB, lights definitely worked then.
HondaJim: not both at same time, ground + one lead at a time, both lit the tester.... just seemed weird to me.
Any ideas how to even go about checking the switch wires? I really really don't want to have to cut into the wiring loom.
Used the tester on the bulbs, basically tested the bulbs like a fuse, there are 4 leads per bulb and each pair tested positive for continuity.
