D1 D1S D1R LED Headlight Bulbs – 70W 22000LM D-PRO Series HID Replacement, 6500K Cool White | 2 Bulbs

Frequently asked questions

• What are D1 D1S D1R LED headlight bulbs?

  
  D1 D1S D1R LED headlight bulbs are LED replacements for factory D-series HID/xenon bulbs that plug directly into the original HID ballast — in this case the Auxbeam D-PRO Series kit rated at 70W, 22,000LM per pair and 6500K cool white. Unlike a halogen-to-LED conversion that needs a new driver, this kit reuses the vehicle’s working factory ballast, so installation takes about 10 minutes with no cutting or rewiring. Browse the LED headlight bulbs catalog by bulb size if you are not sure which D-series size your vehicle uses.
  

• Are D1, D1S and D1R the same bulb, and can this kit fit all three?

  
  Yes — this single kit is listed for D1, D1S and D1R HID bulbs. The difference between the three is the indexing tab angle on the mounting ring: the D1 and D1S positions use a 45° rotation, while D1R uses 30°. Rotate the bulb to the matching position before locking it into the headlight housing, then confirm the beam pattern on a wall. If your vehicle’s original bulb is marked D1S or D1R, this kit is the correct family; use Select Your Vehicle to double-check your year, make, and model.
  

• Do D1 LED bulbs work with the factory HID ballast, and do I need to remove it?

  
  They are designed to plug straight into the original HID ballast, and the ballast stays in the vehicle — there is no need to remove, bypass, or replace it, which is why installation takes about 10 minutes. One condition matters: make sure the factory ballast is working before you install. Because these bulbs depend on the ballast for power, a failed ballast will keep the new bulbs from lighting; diagnose the ballast first rather than assuming the bulbs are faulty. Fitment questions can be sent to customer@auxbeam.com.
  

• Can I install D1S/D1R LED bulbs into a D3S or D3R ballast?

  
  No — never mix them. D1/D1S/D1R and D3/D3S/D3R HID systems use different ballast voltages and are not interchangeable: installing D1S/D1R LED bulbs into D3S/D3R ballasts, or D3S/D3R LED bulbs into D1S/D1R ballasts, can burn out the HID ballast. Check the marking on your original HID bulb or ballast before ordering. If your vehicle uses the D3 family, choose the D3 D3S D3R LED headlight bulbs; the D2 and D4 kits serve other D-series sockets.
  

• How do I know whether my vehicle uses D1S or D1R headlight bulbs?

  
  The fastest check is the marking printed on the original HID bulb or its ballast — it will read D1S or D1R. You can also use Select Your Vehicle to filter by year, make, and model, check the owner’s manual bulb chart, or email customer@auxbeam.com with your vehicle details for a fitment confirmation before you order. Because this kit covers D1, D1S and D1R, the key point is confirming you are in the D1 family rather than D2, D3, or D4.
  

• How bright are D1 LED bulbs compared with factory HID bulbs?

  
  This kit delivers 70W and 22,000LM per pair in 6500K cool white, giving a wider and farther field of view than aging factory HID bulbs, which dim noticeably over time. Brightness is only useful if the pattern is correct, so a 1:1 beam position design and ultra-thin chip copper plate reproduce the original HID focal point for uniform 360° illumination with no black spots, shadows, or glare for oncoming drivers.
  

• Will D1 LED headlight bulbs cause dashboard errors or flickering?

  
  The upgraded driver is CAN-Bus ready and compatible with 99% of vehicle computer systems without error codes, warning lights, or flickering. A few sensitive models may still flicker; this is not a quality issue, and adding a decoder resistor resolves it. Our customer order records show that C10 decoders solve most vehicles, including Ford, Jeep and GMC; RAM, Mercedes-Benz and BMW owners should go straight to C20; for Dodge, start with C10 and move to C20 if flickering remains. Match the decoder to your plug size in the Canbus decoder collection.
  

• How long do D1 D1S D1R LED headlight bulbs last?

  
  They are rated for up to 50,000 hours, supported by a 3X heat dissipation system: upgraded dual copper tubes, a 6063 aviation aluminum lamp body and a silent turbo fan that improve heat dissipation by around 150%. IP68 waterproof construction keeps the beam stable through rain, fog, and snow. Keeping the housing sealed after installation helps the fan and heatsink work as designed.
  

• What should I check before and during installation?

  
  Three checks matter: confirm the factory HID ballast is working (the bulbs rely on it for power), rotate the bulb to the correct indexing angle (45° for D1/D1S, 30° for D1R) before locking it in, and verify the beam pattern on a wall so the cutoff is clean and does not glare. Allow a 1-3cm (0.4-1.18") difference due to manual measurement when comparing dimensions. If anything looks off, the LED bulbs FAQ hub has more installation answers.
  

• What is included in the package, and is a ballast supplied?

  
  The package contains two D1 D1S D1R LED light bulbs (one pair). No ballast or conversion kit is included or needed — these bulbs plug into the vehicle’s existing factory HID ballast. If your vehicle has lost its ballast or it is faulty, that part must be repaired first. For other D-series sockets, see the D2 D2S D2R, D3 D3S D3R and D4 D4S D4R pages.
