BSA Flasher unit

A flasher relay unit for turn signals, listed once in the electrical equipment section of the 1972 catalog.

PN · 19-1055

This is a flasher unit, the electrical relay that makes the turn signals blink instead of just staying lit. It shows up in the electrical equipment section of the parts book with a single catalog listing tied to 1972, so that's the year the record ties it to.

On a bike with indicators fitted, the flasher unit sits in the wiring between the switch and the turn signal bulbs, cycling the current on and off to give you that blinking action. It's a self-contained can-style relay, easy enough to swap if the signals stop blinking or start staying on solid.

Our record on this one is brief, just the single catalog entry and no alternate numbers, so if you're chasing a specific bike or want to cross-check against what's in your parts book, give us a call and we'll confirm it before you order.
