Directionals Question
« on: January 01, 2024, 03:24:43 PM »
Have a 1978 CB750F. Bought some directional signals on Ebay that are in better condition than mine. The ones purchased have 1 wire. The ones one the bike have 2 wires. I get the plug in positive lead. What is the other one? Ground that stays with the housing?
Thanks for any and all responses.

The 2-wire directionals will have sockets for 1157 dual-filament bulbs. These are front directionals, one filament is always on (except when your turn signal is on) as a running light, and the other is the turn signal.

As Alan said, the 2 wires are for the front, running light and turn signals on the other wire.
The single wire are turn signal only, for the rear(stock configuration)

You can pull the guts out of your lights and swap the housings and have the 2 wire, 2 filament sockets and bulbs up front.
