Shop D1S headlight bulb options designed to replace stock D1S HID bulbs with a clear white LED output. This collection includes a dedicated D1S/D1R pair and a multi-size product with a selectable D1S option. Before you add a set to your cart, use the vehicle selector and check the code on your original bulb. Matching the base and factory lighting system matters more than choosing by car brand alone.

Fitment and road-use notice: These are aftermarket LED replacements for vehicles equipped with factory HID headlights. They are not replacement xenon-gas HID capsules, and they do not fit factory halogen bulbs or OEM LED systems. LED conversions may not meet road-use requirements in every housing or location. Use for off-road, show, or race applications where required, and check local laws before ordering.

Check D1S or D1R Fitment First

A vehicle can use different headlight bulbs by model year, trim, and position. That means a Mercedes-Benz or Audi badge alone cannot confirm fitment. Check your owner’s manual, inspect the marking on the original bulb, or use Hawkglow’s Automotive Bulb Finder. Also confirm whether you are replacing the low beams or high beams.

  • Choose the D1S option only if the original bulb is marked D1S.

  • Choose the dedicated D1S/D1R product if the original bulb is marked D1R.

  • Do not use these bulbs in a factory halogen or OEM LED headlight system.

  • Compare the factory connector and available housing space before installation.

The product pages list different power, lumen output, color temperature, and cooling designs. Use those specifications to compare brightness and color, but start with fitment. A higher lumen number cannot make the wrong base fit your vehicle.

Bright, Clear Output Without Guessing at Compatibility

Both products are HID-to-LED replacement choices built around white light and active heat management. Their product pages describe cooling systems intended to support longevity and stable light output.

The RD5 listing also uses a 360° illumination design. Its two published reviews mention a clean beam without dark spots, including one report from a Mercedes-Benz ML 350 owner. Reviews are useful context, but your housing, headlight aim, and electrical system still affect the result.

After installation, check the beam pattern and headlight aim. Correct alignment helps put light on the road while reducing glare for other drivers. If the bulbs flicker, trigger a warning, or fail to stay on, a sensitive CANbus system may need a compatible CANbus LED decoder.

D1S Headlight Bulb FAQ

Are these D1S HID bulbs?

No. These are LED headlight bulbs made to replace compatible bulbs in a factory HID system. They are not traditional HID bulbs that produce light using xenon gas.

Will a D1S bulb fit every Mercedes-Benz or Audi?

No. Bulb size can vary by year, model, trim, and low-beam or high-beam position. Use the vehicle selector and verify the code on the original bulb before ordering.

Can I use these bulbs if my car came with halogen bulbs?

No. These options are designed for compatible factory HID applications. They are not intended to replace factory halogen bulbs or OEM LED headlights.
