YUFANYA Y3-H4 H4/9003/HB2 Projector Headlight Bulb 6000K 30,000LM Canbus Plug-and-Play

The YUFANYA Y3-H4 is a plug-and-play mini H4 projector headlight bulb that delivers a crisp 6000K white beam, clear cutoff line and up to 30,000 lumens for Hi/Lo illumination in most H4/9003/HB2 housings.

This compact retrofit kit combines a hyperboloid projector lens with built-in CANbus decoding and an efficient cooling system to provide a brighter, more controlled light pattern than standard halogen or single-lens LED replacements. Designed to mimic the form factor of traditional halogen H4 bulbs, the Y3-H4 slips into factory sockets with minimal modification while offering a noticeable increase in usable light output and a sharp cut-off for reduced glare.

How does the YUFANYA Y3-H4 improve night visibility?

The hyperboloid projector lens shapes the beam into a defined pattern that concentrates light where you need it and reduces scatter. With multi-chip arrays and a combined output rated up to 30,000 lumens, the Y3-H4 produces a brighter, whiter illumination compared with stock halogen bulbs.

• Hyperboloid projector lens for focused beam and improved center throw
• Multi-chip layout (6+6+3) for dense light output and balanced spread
• 6000K color temperature for clear contrast without excessive blue tint

Will it fit my vehicle and avoid dashboard errors?

The Y3-H4 is engineered as a near 1:1 halogen replacement and includes built-in CANbus decoding to reduce compatibility issues. It’s designed to be compatible with roughly 98% of car models, but some vehicles with advanced vehicle electronics may still require an external resistor or decoder.

• Standard H4/9003/HB2 base mimics original bulb dimensions
• Integrated CANbus decoding to prevent error messages on many ECUs
• Plug-and-play installation in most factory housings; check fit in sealed projector enclosures

How does the Y3-H4 manage heat and durability?

Efficient thermal control is built into the unit with a high-speed silent fan and aviation-grade aluminum housing to dissipate heat quickly. Stable operating temperature helps protect LED chips and electronics, supporting long service life under regular driving conditions.

• Built-in silent high-speed fan for active cooling
• Aviation aluminum alloy body for rapid heat transfer and strength
• Rated life up to approximately 50,000 hours under typical use

What kind of light pattern and legal considerations should I expect?

The Y3-H4’s projector design produces a clear cut-off line on low beam to help limit glare for oncoming traffic while delivering a wide, high-beam spread when toggled. Local laws vary for aftermarket lighting; verify regulations in your area and aim housings for proper alignment to avoid dazzling other drivers.

• Clear horizontal cutoff for low-beam glare control
• Distinct high-beam matrix pattern for extended visibility
• Recommended professional aiming after installation to meet road regulations

Who is this for? The YUFANYA Y3-H4 is a strong option for drivers who want a compact, high-output H4 retrofit that keeps the original socket form factor while improving night-time illumination. It suits owners of older vehicles with halogen housings, retrofitters seeking a projector-style beam without a full housing rebuild, and anyone wanting CANbus-compatible LED performance with reliable thermal management. If your vehicle has advanced lighting modules or strict regulatory requirements, confirm compatibility and aim the beam after installation.
