OXILAM H4/9003/HB2 LED Bulbs Pack of 2 — 6500K Cool White, 1:1 Halogen Fit, 50,000LM Plug-and-Play

OXILAM H4/9003/HB2 LED bulbs are a plug-and-play halogen-size replacement that delivers a brighter, whiter 6500K beam with a 1:1 fit for safer nighttime visibility.

Swap your dim factory halogens for a modern LED upgrade without cutting wires or modifying housings. These OXILAM bulbs are built on automotive-grade chips and an aviation-aluminum body to reproduce the original H4/9003/HB2 footprint while producing a dramatically brighter, cooler light. Designed to balance output, beam shape and thermal management, they aim to provide a clear road view while minimizing glare to oncoming traffic when installed in compatible housings.

How much brighter are these LEDs compared to stock halogen bulbs?

These OXILAM bulbs claim up to a 900% increase in perceived brightness versus standard halogens, producing a crisp 6500K cool white light that enhances contrast and roadside detail. That higher lumen output creates a wider, more uniform field of illumination for many retrofits.

• Rated at 50000LM combined per pair under optimal conditions
• 6500K color temperature for clearer whites and improved contrast
• Optimized chip spacing to mimic halogen beam geometry

Will these bulbs fit my vehicle and install easily?

OXILAM H4/9003/HB2 LEDs use a precise 1:1 halogen footprint, so they seat into factory H4 sockets without trimming or adapter cages on most vehicles. The design emphasizes an exact mechanical fit to retain the headlight reflector/lens performance intended by the vehicle maker.

• Direct plug-and-play H4/9003/HB2 form factor
• No cutting or housing modifications for compatible assemblies
• Support available if a CANBUS decoder is required

How does the bulb control heat and how long will they last?

Thermal performance is handled by an aviation-grade aluminum body and a passive cooling heat sink that dissipates heat continuously, maintaining stable output. That construction, combined with quality LED chips and driver electronics, is aimed at a long service life.

• Durable aviation-grade aluminum housing for heat dissipation
• Passive cooling—no noisy fans to fail
• Estimated long lifespan (manufacturer-rated up to 70,000 hours)

Will these LEDs trigger dashboard errors or cause flicker?

Built-in intelligent IC helps decode signals on many CANBUS systems to reduce flicker and error messages. If your specific vehicle still shows errors, OXILAM offers support and can recommend an external decoder when required.

• Integrated smart IC for improved CANBUS compatibility
• Reduced chance of flicker and bulb-out warnings in many vehicles
• Customer support available for vehicles needing decoders

Who is this for? The OXILAM H4/9003/HB2 LED pair is intended for drivers who want a brighter, whiter headlight upgrade without altering their headlamp housing: commuters, night drivers and anyone replacing worn halogen bulbs. It's a fit for people comfortable checking compatibility with their vehicle’s headlamp assembly and, when necessary, adding a CANBUS decoder. Avoid aftermarket LED retrofits in projector or reflector housings that specify different beam characteristics—always confirm fit and local regulations before installation.
