Vintage Yamaha Reserve Lighting Unit AS1-07 Relay 12V 4020 XS650 RD350 TX650

Vintage Yamaha OEM reserve lighting unit relay module stamped AS1-07 and 12V 4020. Features original zinc-plated metal housing, dual rubber mounting isolation grommets, and attached 3-conductor wiring harness with 3-prong molded connector plug.

This module functions as an automatic safety switch/relay on vintage Yamaha electrical systems to switch headlight power to the high beam filament if the low beam bulb fails. Physical condition is solid with light age tarnish, minor surface patina, and clean connector terminals. Untested.

Fitment: Fits late 1970s Yamaha street models including XS650, XS650S Special, RD350, TX650, and related 12V twin-cylinder motorcycles equipped with the AS1-07 3-pin relay module. Please verify part stampings and plug configuration prior to purchase.
