RANSOTO Xenon Headlight Ballast Kit with D3S 35W Bulb — 6000K, IP68 Waterproof

RANSOTO's xenon headlight ballast control unit kit combines a D3S 35W bulb, igniter, and electronic ballast to restore reliable HID lighting on compatible vehicles. This complete replacement assembly is built to match factory electrical and optical performance for many late-model cars and SUVs. The kit includes the ballast/control module, an igniter, and a D3S bulb rated at 35W and roughly 2500 lumens, with a cool 6000K color temperature. Engineered for tight tolerances and IP68 water resistance, it aims to eliminate flicker, color shifts, or no-light conditions caused by failed ballast electronics.

How does this ballast kit restore HID headlights?

The ballast supplies the precise startup voltage to ignite the xenon lamp and then regulates current to maintain steady output. When the original ballast or igniter starts to fail, symptoms include slow warm-up, intermittent flicker, or complete outage; replacing the whole assembly addresses all three components at once.

• Includes ballast, igniter, and D3S bulb for a full-system swap.
• Produces stable 35W power at 12V with regulated current flow.
• IP68-rated to resist moisture and road spray.

Will this unit fit my car and match factory part numbers?

The RANSOTO assembly is compatible with numerous makes and model years and is designed to cross-reference common OEM part numbers. Review the vehicle fit list and the replace-part numbers to confirm compatibility before ordering.

• Fits specific model years for Cadillac, Dodge, Chevy, Land Rover, Mercedes-Benz, Volvo, and Kia.
• Cross-references OEM numbers like 130732931515, A2229003300, LR050796, and 22791376.
• Intended as a direct electrical and mechanical replacement for listed applications.

What are the key electrical and optical specifications?

The bulb included is a D3S xenon lamp rated at 35W with an approximate lumen output of 2500LM and a 6000K white color temperature. The ballast operates from a nominal 12V source and the assembly is rated to operate across a wide temperature range for durable on-road performance.

• Bulb type: D3S, power: 35W, lumen: ~2500LM.
• Color temperature: 6000K (cool white); beam angle: 360° nominal emission pattern.
• Operating temperature range: -40°C to +80°C; waterproof rating: IP68.

How easy is installation and what should I expect after replacing it?

Installation typically involves removing the old ballast and bulb assembly, mounting the new module in the original location, and connecting the factory harness to the supplied plugs. After replacement, expect immediate, steady light output without the flicker or color shift that signals ballast failure.

• Ships as a plug-and-play kit with matching connectors and mounting points.
• Recommended to handle with care—avoid touching the xenon bulb glass surface.
• Check alignment and aim after installation to comply with local regulations.

Who is this for: Drivers and mechanics who need a complete HID headlight electrical replacement—especially owners of the listed Cadillac, Dodge, Chevrolet, Land Rover, Mercedes-Benz, Volvo, and Kia models—will find this RANSOTO kit useful. It’s aimed at people who prefer replacing the entire lamp/ignition package to quickly restore factory-like performance and reliability without diagnosing separate components. If your vehicle shows HID startup issues, persistent flicker, or one-side outages, this kit provides an all-in-one repair solution backed by RANSOTO's warranty support.
