Direct-fit H4/9003/HB2 LED kit

The Jansicotek A500-N-S1-H4 set replaces halogen H4, 9003 and HB2 bulbs on both driver and passenger sides. Two all-in-one units arrive ready for plug-and-play installation without extra drivers or wiring modifications. Each bulb carries twelve CSP LEDs in a dual-beam layout covering high and low functions.

50-watt set delivering 8000 lumens

Combined output reaches 8000 lumens at a 6000–6500 K pure-white colour temperature. Each bulb draws 25 watts and 4000 lumens while operating on a 9–14.5 V forward-voltage range. The dual-beam pattern spans 61 to 120 degrees, illuminating the road ahead until extreme fog or heavy rain reduces effective range.

Built-in 12,000 RPM fan and aluminium heatsink

A two-ball bearing fan forces air through an aerodynamic vent across the black aluminium housing, sustaining output for a rated 100,000 hours. IP-rated sealing keeps water and dust out of the clear lens. The compact all-in-one body fits the factory headlight cavity, leaving no external ballast to mount.

Questions about this item

Will the 50 W set work with my vehicle's existing 9-14.5 V electrical system without extra wiring?

Yes, the bulbs draw 25 W each and accept 9-14.5 V forward voltage, so they plug directly into the factory H4/9003/HB2 sockets.

How can I verify the 6500 K output is performing correctly after installation?

Check for a pure-white 6000-6500 K beam with a 61-120° spread and confirm both high and low beams illuminate using the built-in dual-beam switching.

Does the box include everything needed for a plug-and-play H4/9003/HB2 swap or must I buy a separate driver?

The set of two bulbs comes with integrated current-control drivers and a 12,000 RPM cooling fan, so no external driver or harness is required.
