Frequently Asked Questions

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

A: This H4 / 9003 / HB2 Bi-LED projector bulb is designed for LHD (left-hand drive) vehicles and motorbikes running DC 12V systems. It fits the vast majority of cars and motorcycles with an H4 headlight socket. Always confirm your vehicle's socket type and voltage before installation.

Q: Will this bulb trigger a dashboard warning light?

A: The bulb features built-in Canbus technology compatible with approximately 99% of vehicles, preventing error codes or flickering. For particularly sensitive vehicle models, an additional external Canbus decoder may be required (sold separately).

Q: How does the cooling system work on this LED bulb?

A: The bulb uses a dual-stage cooling system: sintered copper heat pipes rapidly draw heat away from the LED chip, while a 12,000 RPM turbine fan and hollow carved radiator — all housed in a 6063 aviation aluminum body — efficiently dissipate that heat. This system helps prevent light decay and supports a lifespan of over 50,000 hours.

Q: What color temperature is 6000K and what does it look like?

A: 6000K produces a crisp, pure white light with a very slight cool/blue tint. It offers excellent road contrast and a modern, premium appearance compared to standard halogen bulbs, improving nighttime visibility on streets and highways.
