Philips D3S Xenon Vision Headlight Bulb

42403VIC1 | 35W | 42V | Single Bulb

Replace a failed D3S xenon headlight bulb with the Philips Xenon Vision 42403VIC1. Designed for compatible original xenon headlights, this replacement combines Philips lighting technology with a practical single-bulb pack.

Replace one bulb while matching the existing light colour

Philips developed Xenon Vision for one-at-a-time replacement: its single-lamp replacement technology is designed to match the colour temperature of the unchanged xenon lamp. This makes it an economical option when only one bulb has failed. The final appearance can vary with the age, type and condition of the remaining bulb.

Philips quality and durable quartz glass

Philips supplies lighting to major vehicle manufacturers and brings that automotive lighting experience to its replacement bulb range.

• UV protection: Philips' anti-UV coating helps protect headlight components from ultraviolet radiation emitted by the lamp.
• Quartz glass construction: Stronger than conventional hard glass, with resistance to temperature extremes and vibration.
• Thermal shock and humidity resistance: The quartz glass is designed to withstand sudden temperature changes, including those caused by moisture contacting hot glass. A damaged or leaking headlamp must still be repaired.

ECE approved for compatible xenon headlights

Philips lists this bulb as ECE certified. It is intended as a replacement in an approved headlamp designed for D3S xenon bulbs, using the correct ballast.

Technical specifications

Check compatibility before ordering

Confirm that your existing bulb is marked D3S. Vehicle model alone does not confirm fitment, as headlight options can differ. D1S, D2S and D4S bulbs are not substitutes for D3S.

Frequently asked questions

Do I have to replace both bulbs?
Philips Xenon Vision is specifically designed for single-lamp replacement. If the other bulb is also dim or deteriorating, replacing both may still be appropriate.

Is this a 6000K styling bulb?
No. Philips specifies a colour temperature of up to 4300K for this model.

Does the pack include a ballast?
No. It contains one D3S bulb; a separate replacement headlight ballast is not included.

Please note: This listing is for one bulb, not a pair. Vehicle photographs illustrate the lighting application and do not confirm vehicle fitment.
