Advantages

This xenon bulb offers exceptional light output compared to traditional halogen alternatives, resulting in a wider and longer reach on the road. The precise engineering of the PK32d-2 base ensures a perfect fit and correct alignment within the headlight housing, which is critical for preventing glare to oncoming traffic. Its durable construction is designed to withstand the vibrations and thermal stresses typical of automotive environments, ensuring a long service life and consistent performance throughout its operation.

Suitable for

• Replacement of faulty or dimmed D1S xenon headlight bulbs
• Upgrading factory-fitted xenon lighting systems
• Improving visibility for night-time driving
• Vehicles equipped with D1S projector or reflector headlight units

When it may not be suitable

This bulb is exclusively designed for vehicles with factory-installed D1S xenon systems and is not compatible with halogen or LED headlight assemblies. It should not be installed in vehicles that do not have the necessary ballast or igniter system required for xenon discharge lamps.

Key specifications

• Power rating: 35W
• Base type: PK32d-2
• Technology: Xenon discharge
• Application: Headlight

How to use

Installation should be performed while the vehicle is powered off and the headlight switch is in the off position. Access the rear of the headlight assembly, remove the protective cover, and carefully disconnect the igniter from the old bulb. Rotate the bulb to unlock it from the housing and replace it with the new unit, ensuring it is seated correctly before reconnecting the igniter. It is recommended to handle the glass part of the bulb with clean gloves to avoid leaving oils that can cause premature failure.

What to consider before purchase

• Verify that your vehicle manual specifies a D1S bulb type
• Check if your headlight system uses a 35W ballast
• It is recommended to replace xenon bulbs in pairs to ensure uniform color and brightness

Usage recommendations

Always replace xenon bulbs in pairs to maintain balanced light output and color temperature across both headlights. Avoid touching the glass bulb with bare fingers, as skin oils can create hot spots and significantly reduce the lifespan of the lamp.
