OSRAM Original Line P21/4W bulb (7225)

OSRAM Original Line 7225 is a high-quality P21/4W twin filament bulb designed to meet the strict original equipment requirements of car manufacturers (OEM). This bulb is equipped with two filaments, which allows two different light functions in one and the same lamp.

The P21/4W bulb is typically used in combined brake and tail lights or rear fog and tail lights. Its 21 watt filament is responsible for the strong brake or fog light, while the 4 watt filament provides the constant tail light. The special BAZ15d base is equipped with asymmetrical pins that are placed at different heights and angles. This ensures that the bulb cannot be installed in the wrong direction or replaced with the wrong bulb type.

Key features:

• Genuine OEM quality: The same bulb that is used in many cars when originally installed at the factory.
• Dual-function design: 21W and 4W filaments enable a safe and clear light signal.
• Special BAZ15d base: Asymmetrical pins ensure a perfect and secure fit.
• Durable and reliable: OSRAM quality guarantees a long service life and excellent vibration resistance.
