Check your bulb size before ordering. This kit is for H4/9003/HB2 high/low-beam applications. Match the three-tab flange and three-terminal connector to your original bulb. Use our Bulb Application Guide, then confirm your existing bulb, connector and room for the fan, external driver and wiring. CANbus compatibility varies by vehicle; additional adapters or electrical measures may be needed.

Replace your factory H4/9003/HB2 halogen bulbs with this GENSSI H4/9003/HB2 LED kit. Delivering 50,000 lumens total per pair and 75W per bulb (150W total per pair), these 6000K white bulbs use 75MIL 6075 LED chips for high-output lighting.

External wired drivers and matching H4/9003/HB2 connectors allow direct plug-and-play connection to factory wiring without splicing.

Fitment & Installation Guidance
Switch off the lights and let the existing bulbs cool before handling them. Follow your vehicle manual for access and bulb replacement. After installation, test both lights and check headlamp aim, dashboard warnings and flicker.
Before ordering or installing, look up your vehicle in our Bulb Application Guide and compare bulb bases using our Bulb Type Chart & Cross-Reference. Confirm that your housing uses a standard H4/9003/HB2 halogen bulb.
These bulbs are designed as a direct plug-and-play replacement for matching factory H4/9003/HB2 halogen sockets with no wire splicing required. Because headlight assembly access, bulb retainers, dust covers, and housing clearance are not universal, always check that your headlamp assembly has enough physical space for the aluminum body, built-in fan, and external wired drivers. Vehicle-specific retainers or additional electrical measures may be needed; confirm requirements before installation.
