Product details
The Link International 6V 21/5W BAY15D is a dual-filament replacement stop/tail bulb designed for motorcycles and light vehicles running a 6-volt electrical system. The BAY15D bayonet base features offset locating pins to ensure correct polarity alignment when fitting.
Suited to classic, vintage, and older-model motorcycles that retain their original 6V electrics, this bulb offers a direct, like-for-like replacement without modification. The 21W filament activates under braking; the 5W filament provides continuous tail illumination.

Solid steps show periods confirmed by the store’s change-only price history and completed crawl record: if the price had changed at a check, another point would appear. Dashed steps show overdue periods with no completed crawl confirmation. Every line stops at that listing’s last confirmed check and is never extended to today. Prices are not live and may have changed since the last point shown.
