Refined heatsink streamlines heat away from the LED 13000RPM TurboCool fan ?Shoots cold air directly through an aerodynamic vent to evenly cool every component. Built in IC Circuit (Current Regulator)-Prevents LED Damage from Voltage Variations & Spikes 80% Less Power Consumption Important Notice: For some European vehicles equipped with a CANBUS systems, our LED Headlights may not light up or flicker. Anti-flicker Relay Harness is needed to prevent it.Just in case?please check the size before you made the order? 1. 360-degree light on both sides, with the reflection of the original lamp cup, the light utilization rate is increased by 50%, and it starts instantly. Special material to solve the problem of high temperature heat dissipation. 2. LED integrated design, non-destructive installation, easy installation. 3. Directional pressurized air cooling system + high-speed silent fan for forced cooling, 6500 cycles/min, extremely fast cooling, effectively prolonging the life of the light source, and making the light decay very, very low. 4. The light source adopts imported custom COB light source, packaged with copper substrate, and the light efficiency reaches 130LM/W. 5. Energy-saving design, 36W achieves 3800 lumens of luminous flux, which is brighter and more energy-efficient than ordinary headlights. 6. LED light, 60% energy saving than halogen light, 3 times brighter. 7. Integrated design of far and near light 8. The lamp has a built-in driver, and the original car is docked, no need to break the line and change the line 9. The lamp is powered by DC, input voltage: DC 9-36V 10.30000 hours long service life. Package included: 2 x LED headlight
