Mercedes Sprinter D1S Xenon Headlight Bulb – Hudson Premium | NCV3 | #N10566103

A failed D1S xenon bulb on a Mercedes Sprinter leaves the headlight dark despite a functioning ballast — no arc, no light, and a safety and inspection issue that needs immediate attention. This is the Hudson Premium D1S xenon headlight bulb for NCV3 Sprinters and other Mercedes-Benz vehicles equipped with D1S xenon headlights, a direct replacement that restores high-intensity discharge illumination.

What This Part Does

The D1S is a high-pressure xenon discharge bulb with an integrated high-voltage igniter — the "S" designation indicates a built-in starter that interfaces directly with the xenon ballast. The D1S uses a mercury-containing xenon-metal halide arc to produce approximately 3,200 lumens of brilliant white light with a color temperature around 4,200K. Over its service life the electrodes gradually erode and the arc tube darkens, progressively reducing light output and making arc strikes increasingly unreliable before the bulb eventually fails.

Common Symptoms of a Failing D1S Bulb

• Headlight that does not illuminate with the ballast and wiring confirmed good
• Headlight that requires multiple strike attempts before sustaining the arc
• Noticeably reduced or yellowed output compared to the opposite side
• Arc that fails within seconds of striking

When to Replace

Replace when the bulb fails to illuminate or produces degraded output with the ballast confirmed working. Replace in pairs for consistent light output. Never touch the quartz arc tube with bare fingers.

Fitment

• NCV3 Mercedes-Benz Sprinter with D1S xenon headlights
• Other Mercedes-Benz vehicles with D1S xenon headlight systems

✔ D1S with integrated igniter — confirm your headlight uses D1S before ordering
