Replace the taillight or stop/tail bulb on your vintage scooter or motorcycle with this 6V 21/3CP Dual-Filament Taillight Bulb. This S25-style incandescent bulb uses a BAY15d offset bayonet base (15mm / 0.6" base diameter) and features two filaments — a brighter stop filament (21CP) and a dimmer tail filament (3CP) — making it the correct replacement for combined tail/brake light applications on 6-volt electrical systems.
Commonly used in vintage Vespa, Honda, and other classic scooters and motorcycles with 6-volt lighting systems. Use the Scooterworks bulb chart to confirm fitment for your specific model.
