Automotive HID Xenon bulb Ledvance D3S 42V 35W Cool Blue

Ledvance D3S 42V 35W Cool Blue is an automotive HID xenon replacement bulb designed for vehicles equipped with D3S fittings. Rated at 42 volts and 35 watts, this bulb produces a cool blue light that closely matches higher color temperatures used to improve on-road visibility and give headlights a modern, neutral-white to slightly blue appearance. It is intended as a direct replacement for compatible OEM D3S xenon bulbs and restores original lighting performance where high‑intensity discharge systems are specified.

Advantages

The bulb offers consistent luminous output for stable beam patterns and color rendering in compatible HID headlamp systems. Its cool blue light tone aids contrast perception under certain driving conditions and contributes to a contemporary vehicle appearance. The construction follows automotive fitment standards for D3S sockets, allowing straightforward replacement without modification of the headlight housing.

Suitable for

• Replacement of OEM D3S xenon bulbs in passenger cars equipped with D3S HID systems
• Restoring headlight performance after bulb failure or degradation
• Applications where a cooler, neutral-white to slightly blue light tone is desired

Key specifications

• Technology: High-intensity discharge (HID) xenon
• Fitting type: D3S

How to use

Switch off the vehicle and allow the headlight assembly to cool before replacing the bulb. Access the D3S socket according to the vehicle manufacturer’s instructions, remove the old xenon lamp, and insert the Ledvance D3S 42V 35W Cool Blue bulb into the fitting until it is seated securely. Reconnect any retaining clips or covers and test the headlight operation. Ensure the vehicle’s ballast and headlamp wiring are compatible and in good condition prior to installation.

Recommendations

Use only in vehicles specified for D3S HID bulbs and with functional ballasts; do not handle the glass bulb surface with bare hands—use gloves or a clean cloth to avoid contamination and premature failure. Follow local regulations for headlight color and alignment, and have headlight aim checked after installation if necessary.
