Xenon HID Headlight Ballast for Cadillac Escalade 2007-2013 & D1S Bulb Part New Set
Restore reliable nighttime visibility with a complete dual‑set HID replacement kit engineered for direct OE integration. This package delivers two fully assembled modules, each combining a high‑capacity ballast, a precision ignition coil, and a matched D1S xenon quartz bulb into a single drop‑in unit. Eliminate the mismatched component failures that cause flickering, delayed startup, or premature burnout in aging factory assemblies.
Designed as a direct cross‑reference for Cadillac Escalade HID systems, this set replaces OEM identifiers 12767670 and 15782392. It also matches critical supplier part numbers including BMW 63 12 6 937 223, Mercedes‑Benz A 000 821 10 61, Land Rover YWC 500480, and Volkswagen 5M0 907 391. Factory HID circuits typically degrade between 60,000 and 80,000 miles due to electrolyte depletion in the ballast capacitors and voltage regulator wear. Swapping only the exhausted lamp rarely extends service life because the original igniter and driver electronics share identical operational hours. Installing pre‑matched components restores consistent arc current delivery and stable color temperature across both front corners.
Verified platform coverage includes:
- Cadillac Escalade, Escalade ESV, and Escalade EXT (2007–2013) with 6.0L and 6.2L powerplants
- BMW 5‑Series (E60/E61), 7‑Series (E65/E66), and X6 (E71) equipped with factory xenon optics
- Mercedes‑Benz G‑Class, S‑Class, Sprinter, and CLS models utilizing stock D1S configurations
- Jaguar XF/XKR, Land Rover Range Rover, Hyundai Genesis/Equus, and select Chrysler, Dodge, and Freightliner van platforms
Proper fitment requires matching your existing harness connector shape and confirming the stamped headlamp housing code before removal. Extract the assembly, disconnect the high‑voltage wiring plug, anchor the new module using the factory mounting brackets, and reseat the connector until the locking tab engages. Handle each bulb strictly by the metal base or plastic collar to prevent silicone oil transfer that accelerates UV glass darkening under thermal cycling.
