Description
Overview:
The 12 V 21/5 W Stop/Tail Fog Side/Flasher Bulb is a dual‐filament incandescent lamp supplied in a pack of 10 for workshop and fleet maintenance. Each bulb has a BAY15d SBC (offset index) bayonet base with twin contacts for a secure, correct‐orientation fit in suitable lamp holders. The 21 W filament serves brake, indicator or fog functions, while the 5 W filament covers tail or side/marker lighting, helping keep machines visible on and off site. Built with a glass envelope and metal bayonet cap, it is a practical replacement for plant, site vehicles and garden machinery, including models such as 100C-1 and 8050 ZTS. It is a direct replacement for OEM No. 720/10038 where specified.
