H7 LED Headlight Bulbs – 120W 25000LM GX Series, 6500K Cool White, 650% Brighter | 2 Bulbs

Frequently asked questions

• Will these H7 LED bulbs fit my vehicle?

  
  These bulbs fit vehicles whose headlights use an H7 single-beam socket. Two ways to confirm: open the Select Your Vehicle tool and enter your year, make, and model, or email customer@auxbeam.com with your vehicle details and we will check fitment for you. Note that some H7 cars also need a retainer holder—see the next question.
  

• Do I need an H7 retainer holder adapter?

  
  It depends on your headlight housing. Based on our order records, vehicles such as VW, KIA, Hyundai, BMW, and Mercedes-Benz usually need an extra H7 retainer holder adapter to lock the bulb in place, while many other models accept the bulb directly. Check your current bulb’s locking ring before ordering—if it uses a separate metal or plastic holder, add the matching H7 retainer holder to your cart.
  

• Can I use one pair for both high beam and low beam?

  
  H7 is a single-beam socket: one pair covers either your high beam or your low beam, not both. If your car uses H7 for both positions, order two pairs. For other sockets in the same vehicle, browse the LED headlight bulbs collection by bulb size to find the matching pair.
  

• How is the GX Series different from other Auxbeam H7 series?

  
  The GX Series is our 120W/25,000LM flagship line for this socket: 75 mil 7035CSP chips, aviation aluminum body with turbo fan cooling, and a built-in CAN-Bus driver. Auxbeam also offers other H7 series at different brightness and price points—to compare them side by side, visit the H7 bulbs collection, which lists every series for this socket in one page.
  

• My dashboard shows an error or the bulbs flicker. How do I fix it?

  
  The built-in driver is compatible with 99% of vehicle computer systems, but a few sensitive brands—Mercedes-Benz, BMW, Volvo, Dodge, Ford Fusion/Focus/Escape—may flicker or throw a bulb-out warning. This is not a quality issue; adding a decoder resistor solves it. Based on our order records, C10 covers most vehicles including Ford, Jeep, and GMC; RAM, Mercedes-Benz, and BMW should take C20 directly; Dodge owners can start with C10 and switch to C20 if needed. Both models are offered as add-on options on this page, or separately in the Canbus decoder collection.
  

• The original dust cover will not close after installation. What should I do?

  
  This can happen on some housings: the LED bulb’s cooling fan occupies more space than the halogen bulb did, so the rigid original dust cover may not fit back. The fix is simple—replace it with a flexible silicone dust cover, which seals the housing while leaving room for the fan. Order one from the dust cover collection; installation takes less than a minute.
  

• How long does installation take?

  
  Most drivers finish both sides in about 10 minutes. The bulb is an almost 1:1 mini match to the halogen size with a 360°-adjustable base ring, so it locks in like the original: twist out the old bulb, seat the new one, connect the plug to the external driver. Add a few extra minutes if your model needs a retainer holder or a silicone dust cover.
  

• Are these bulbs waterproof and durable?

  
  Yes. The bulbs are rated IP68 waterproof and operate from -45℃ to 150℃, standing up to rain, snow, and car washes. The aviation 6063 aluminum body with hollow-carved heat sink and 12,000RPM turbo fan keeps temperatures low for a lifespan of over 50,000 hours. They are covered by Auxbeam’s 2-year warranty; if anything goes wrong, contact customer@auxbeam.com or visit the LED bulbs FAQ hub.
  

• Why is the beam pattern important for H7 bulbs?

  
  H7 housings rely on the bulb’s light-emitting point sitting exactly where the halogen filament was. The GX Series uses an ultra-thin surface interval to place its two chips in the filament position, projecting a super-focused beam with a clear cut-off line. A poor LED copy scatters light and blinds oncoming drivers; a correct beam pattern keeps the light on the road—that is why we highlight it over raw brightness.
  

• What is included in the package?

  
  The package includes two H7 LED headlight bulbs with their external driver units, ready to install. Retainer holders, silicone dust covers, and C10/C20 decoders are optional add-ons—choose them on this page if your vehicle needs one, or pick them up later from the corresponding collections.
