In the throes of fitting a lovely LED headlamp to my V7iii Special, and need to do some minor wiring mods. Can/will a knowledgeable person please give me a definitive answer on the pin polarity (hi, lo, earth) of the pins on a standard H4 bulb. There's untold conflicting info on the intergoogle, and I don't want cut the wrong wires. I can't run the bike to power up the headlight because it's somewhat disassembled for other, not the least of which is running wiring for spotties and for my trailer wiring.
Looking from the PIN side of a standard H4 bulb:
I have a left pin, a top pin and a right pin. I need to know which pins correspond with high, low and earth.
