H4 Mini Bi-LED Projector Headlight Bulb – 70W | 6000K | CANbus | 9003 / HB2

Upgrade your motorbike or car's lighting with this high-performance H4 Mini Bi-LED Projector Headlight Bulb. Delivering a powerful 70W output and a crisp 6000K daylight-white beam, this single LED lens unit replaces your factory halogen bulb for dramatically improved road visibility on both high and low beam settings.

Built for durability and compatibility, the Aviation 6063 aluminum housing and sintered copper heat pipe technology work in tandem with a 12,000 RPM turbine cooling fan to keep temperatures in check — helping maintain consistent brightness and extend bulb lifespan to 50,000+ hours.

Key Features

Dual Beam Design: Single lens handles both high and low beam — no need for two separate bulbs.
70W Bright Output: 6000K crisp white light for excellent road illumination in all conditions.
CANbus Compatible: Built-in CANbus support means no error messages or flickering on the vast majority of vehicles. Note: some sensitive models may require an additional CANbus decoder.
Advanced Cooling System: Aviation-grade 6063 aluminum body + sintered copper heat pipe + 12,000 RPM hollow turbine fan prevent heat buildup and light fade.
Wide Operating Temperature: Engineered to perform reliably from -40°C to +80°C (-40°F to +176°F).
Plug-and-Play Fitment: 9003 / HB2 / H4 socket — direct replacement, no wiring modifications needed for most vehicles.
LHD Configuration: Designed for left-hand drive vehicles and motorbikes.
DC 12V Compatible: Perfect for standard automotive and motorcycle electrical systems.

Frequently Asked Questions

Q: Is this H4 LED bulb compatible with my motorcycle or car?

A: This H4 / 9003 / HB2 LED projector bulb fits any vehicle using the standard H4 socket, including most motorcycles, cars, and light trucks. It is designed for left-hand drive (LHD) vehicles. The built-in CANbus circuit is compatible with approximately 99% of vehicles; some highly sensitive electrical systems may require an additional external CANbus decoder to eliminate any warning indicators.

Q: Does this bulb replace both high and low beam?

A: Yes! The mini bi-LED projector design integrates both high beam and low beam into a single bulb unit. You only need one bulb per headlight housing — no additional adapters or dual-bulb setups required.

Q: How does the cooling system work and why does it matter?

A: The bulb uses a three-stage cooling solution: a 6063 aviation-grade aluminum body for structural heat dissipation, a sintered copper heat pipe to rapidly channel heat away from the LED chip, and a high-speed 12,000 RPM turbine fan. Together, these keep the LED at a stable operating temperature, preventing brightness degradation over time and ensuring a lifespan of 50,000+ hours.

Q: What color temperature is 6000K, and is it road-legal?

A: 6000K produces a bright, crisp white light with a very slight cool-blue tint, similar to midday daylight. It provides excellent contrast and visibility compared to standard yellow halogen bulbs. Road legality varies by country and region — always check your local vehicle lighting regulations before installing aftermarket LED headlight bulbs.
