Direct-fit H4/9003/HB2 LED kit

This set of two bulbs replaces halogen H4, 9003 or HB2 dual-beam headlights on cars, trucks, vans, SUVs, ATVs and motorcycles. Each unit integrates the driver and a 12,000 RPM cooling fan in an all-in-one housing. The 6000 K pure-white output suits drivers who want a straightforward halogen upgrade without external ballasts or wiring changes.

IP68 sealed, fan-cooled thermal management

The aluminium heatsink and built-in two-ball fan move air through an aerodynamic vent to keep the CSP LEDs stable during extended high-beam or low-beam use. Operating voltage spans 12 to 24 V with a 9 to 14.5 V forward range, drawing 25 W per bulb for 50 W total per set. IP68 rating protects the internals from water and dust ingress.

Plug-and-play dual-beam replacement

The bulbs fit the existing H4/9003/HB2 sockets directly and support both high and low beam functions from a single unit. Dual-polarity design and constant-current driver simplify installation across 12 V and 24 V vehicle electrical systems. Rated lifespan reaches 100,000 hours. Not suited for vehicles requiring separate high-beam and low-beam capsules or proprietary headlight modules.

Questions about this item

How do I install the H4/9003 LED bulbs and what is the step most people miss?

Plug the bulbs directly into the H4/9003 socket; the dual-polarity design allows either orientation, so no wiring changes are needed.

What maintenance or replacement will the cooling fan need later?

The built-in dual-ball fan runs at 12000 RPM for the rated 100000-hour lifespan; no scheduled maintenance is required unless the fan fails.

What is the first limit that appears during sustained high-beam use?

Continuous 25 W operation per bulb relies on the fan and aluminium heatsink; if airflow is blocked, thermal protection will dim the output.
