Jansicotek AKAS T1-9004 9004/HB1 Hi/Lo LED Headlight Bulbs 70W 7200LM 6000K Cool White Set of 2

What these bulbs replace

This set of two 9004/HB1 LED headlight bulbs fits the dual-beam socket used for both high and low beam on many vehicles. Each bulb draws 35 watts and produces 3600 lumens at 6000K cool white, giving a combined 70 watts and 7200 lumens per pair. The convex LED chips and built-in current control operate on a 9 to 14.5 volt range with dual-polarity support.

Who gains and who looks elsewhere

Drivers wanting a direct halogen replacement with a 61 to 120 degree beam spread and a 50000-hour rated life will find the output and colour temperature suitable. Buyers who need a different socket type, a warmer colour, or a single-beam configuration cannot use this kit. Vehicles that require additional CANbus resistors or professional headlamp removal should verify compatibility before ordering.

Build fit and clearance

The bulbs include a 12000 RPM IP67 turbo fan and a heat sink that runs 30 percent cooler than standard designs, so they need enough room behind the headlamp housing for the fan and driver module. The plug-and-play base connects to the factory wiring without splicing, and the dual-polarity circuit works with both positive and negative ground systems. Ensure the housing depth can accommodate the fan assembly before installation.
