OSRAM Original P21/4W 12 volts BAZ15D Signal Lamps, 2-Pack

The OSRAM Original P21/4W 12V BAZ15D Signal Lamps, 2-Pack, provide a direct replacement for factory automotive signal lights. This incandescent signal lamp fits vehicles requiring a BAZ15D base for proper mechanical and electrical integration. It is designed for dual-function applications such as brake, tail, or indicator lighting. The traditional filament construction offers a straightforward solution for restoring standard visibility on the road. Vehicle owners and professional repair shops can use these units to maintain original-equipment lighting performance.

Each bulb operates at 12 V and draws 21 W of power during use. A durable metal base ensures secure physical seating and stable electrical contact within the vehicle housing. The 2-pack format supplies two matching bulbs to complete left and right side repairs at the same time. These components fit traditional automotive electrical architectures without requiring specialised adapters. Standard incandescent technology allows a simple plug-in installation into compatible sockets.
