9005/HB3 LED Headlight Bulbs – 240W 40000LM GX-ULTRA Series, 6500K Cool White | 2 Bulbs

Frequently asked questions

• Is 9005 the same bulb as HB3?

  
  Yes — 9005 and HB3 are two names for the same single-beam headlight socket, typically used for high beams or fog lights. It is a single-function bulb: one bulb, one beam. The Auxbeam GX-ULTRA pair on this page replaces the stock 9005/HB3 halogen bulbs one-for-one, and the decoder options on this page are listed for the same socket family (9005/HB3/H10). To confirm which position your vehicle uses, check Select Your Vehicle or email customer@auxbeam.com with your vehicle’s details.
  

• Which vehicles should not use the GX-ULTRA 9005 bulbs?

  
  The GX-ULTRA series is a high-power bulb designed for cars and SUVs — it does not fit Pickup Truck / GMC / Ford / Chevy / Dodge Ram, because the model system mismatch will cause the bulbs to go out. If you drive one of those vehicles, we recommend the GX Series LED headlight bulbs instead — same plug-and-play fitment, calibrated for those platforms. Not sure which series fits? Select Your Vehicle shows the recommended option for your year, make, and model.
  

• Do I need to replace my car fuse before installing these 240W bulbs?

  
  The GX-ULTRA series draws high power, so if your vehicle has old or small-rated fuses, replace the relevant fuse before installation to avoid burning it out. The recommended replacement is a fuse of 10A or above, and no more than 20A. Vehicles with standard modern fuses typically do not need any change — this is a precaution for older wiring setups, not a requirement for every car.
  

• How do I confirm my vehicle uses a 9005/HB3 bulb?

  
  Two quick ways: use Select Your Vehicle and filter by year, make, and model — the tool shows exactly which sockets your vehicle uses; or email customer@auxbeam.com with your vehicle’s year, make, and model, and we will confirm before you order. The 9005/HB3 socket is a single-beam bulb: if your vehicle pairs a 9005 high beam with an H11 low beam, our 9005+H11 combo kit covers both sockets in one order instead of buying two separate pairs.
  

• What is the difference between GX-ULTRA and the standard GX series?

  
  The GX-ULTRA series is the flagship of the GX Evolution family: 240W and 40,000LM per pair versus 120W and 25,000LM on the standard GX — about 950% vs 650% of halogen brightness. Both are wire-controlled designs, but GX-ULTRA steps up the cooling hardware with a bold 4.0mm dual copper tube and a 20,000RPM fan for a 55,000-hour lifespan. Browse the GX-ULTRA collection or the GX Series collection to compare sockets; if you want dual-color switching, see the GX Bi-Color collection.
  

• Will these 9005 LED bulbs cause error codes or flickering?

  
  The upgraded smart IC driver is CAN-Bus ready and compatible with 99% of vehicle computer systems without error codes. A few sensitive models — such as Mercedes-Benz, BMW, Volvo, Dodge, Ford Fusion, Ford Focus, and Ford Escape — may flicker after installation; this is not a quality issue, and adding a decoder resistor resolves it. Based on our customer order records: the C10 decoder solves most decoder cases, including Ford, Jeep, and GMC; RAM, Mercedes-Benz, and BMW should choose C20 directly; for Dodge, start with C10 and switch to C20 if flicker persists. Both C10 and C20 decoder options can be added on this page when ordering, or bought separately from the Canbus decoder collection.
  

• Do these bulbs fit under the original dust cover?

  
  The bulbs are built at the same size as the original halogen bulbs, but the cooling fan adds extra length, so on some vehicles the original dust cover cannot be reinstalled after fitting. The fix is simple: replace the stock cover with a silicone dust cap from our dust cover collection — it keeps the housing sealed against water and dust while leaving room for the fan.
  

• How bright are the GX-ULTRA 9005 bulbs compared to halogen?

  
  Each pair outputs 240W and 40,000LM — about 950% brighter than halogen bulbs, roughly 10 times the light output — the brightest level in the Auxbeam GX family. On unlit roads that translates to seeing signs, deer-crossing zones, and lane lines far earlier than dim yellow halogen light allows, while the 1:1 factory beam position design keeps all that output concentrated on the road with no dark spots and no glare into oncoming traffic.
  

• How long do the GX-ULTRA bulbs last, and are they waterproof?

  
  The GX-ULTRA series is rated for up to 55,000 hours. Heat is handled by the 4X heat conduction stack: an all-in-one aviation 6063 aluminum body, a bold 4.0mm dual copper tube, and a 20,000RPM super-speed silent fan that protects the chips at 240W output. The bulbs also carry an IP68 waterproof rating and a wide operating temperature range, standing up to rain, dust, frost, snow, and car washes for years of nightly driving.
  

• What warranty and shipping terms apply to this GX-ULTRA pair?

  
  This pair is covered by a 2-year warranty (clearance items excluded) and a 30-day hassle-free return policy. Orders ship from our US warehouses, with free shipping on US orders over $19.90.
