OE Replacement: AL 7317408

Restore your factory HID headlight performance with the Bosch / AL Model 7317408 HID Ballast (BL200), an OE-style replacement designed for many modern BMW vehicles equipped with factory HID headlights. Built to meet or exceed original specifications, this ballast provides reliable operation and a direct-fit solution at a fraction of the dealership cost.

OEM-Grade Replacement

The Bosch / AL 7317408 ballast is commonly found as original equipment on various BMW HID headlight systems.

Designed as a replacement for the factory unit, this ballast delivers:

• Proper HID bulb power management
• Stable light output
• Reliable ignition and operation
• Direct-fit compatibility with applicable applications

While this replacement ballast is not manufactured by the original vehicle manufacturer, it is engineered to match OE specifications and provide identical fitment and functionality.

Restore Your HID System Without the Dealership Price

Factory HID ballasts can fail over time due to normal wear, heat cycles, and age. Replacing them through a dealership can often cost hundreds of dollars.

This high-quality replacement offers the same performance you expect from a factory ballast while providing a much more affordable repair solution.

Replace Aging Components Together

Most HID systems have a limited service life. If one component has failed, other bulbs or ballasts may not be far behind.

To avoid repeating the same labor-intensive process, many enthusiasts choose to replace aging HID components together, saving time and avoiding the need to remove the bumper and headlight assembly multiple times.

Important Compatibility Note

Some vehicle models may use different HID ballast versions depending on:

• Production date
• Vehicle trim level
• Factory equipment options

Always verify the part number on your existing ballast before ordering to ensure proper compatibility.
