Automotive LED headlamps advantages:1. LED lights than traditional halogen energy, more power.2. lamp brightness and proximity, but the LED lights light up without delay, to enhance road safety. Instant start no strong currents impact, effectively protecting the car comes with a battery, improving battery life of more than 30%. 3. Fast cooling, the appearance of the most advanced design, thermal structure ingenious and reasonable.Less , power driver with wide voltage constant current mode, the car can respond to a of voltage instability, the effective protection of normal use Led efficient and simple structure. Fewer Components damaged, repair the probability is very low, compared with HID ballast repair lower than 80%. 4. Heating temperature is low, protect the car. working temperature up to 800 -1000 , the main reason for the car ignition.5. LED car headlights simple structure, fewer parts than lamps, significantly lower than the lamp failure rates !6. Automotive LED headlamps color temperature balancing. The bulbs in the same color to clear, about 6000K. For a few years make cars(About 0.1%),Germany Cars,,,,,, Cars and DRL Model may need add Load Resistors(Not including) to stop flickering Issue or fix error message. 4-Sided LED Bulb,Each Bulb Total have 4pcs Long COB LED Chips.Plug and Play, Canbus Error Free For 99% of Cars, Built-in Fans, No Other Fans and Ballasts Required.Built-In Cooling Fans,Smart Efficient Cooling System Fast Heat Dissipation.High quality Aluminum heat dissipation ensures the secure temperature range.Low Power Consumption than Halogen bulb, Energy Saving.Low Voltage Protection, High Precision Constant Current driver Chip.Shakeproof and Long lasting up to 50,000 Hours.

As a safety precaution, make sure that the car has had time to cool down properly before starting the installation process. 2. Put the vehicle into park or make sure it is securely in gear. 3. Make sure to have the ignition turned off and the keys removed. 4. Be careful to avoid , especially when turning on or off the vehicles lighting. 5. Be careful to avoid crushing or cutting the bulbs. Also make sure to not Contact the bulbs with your fingers, as this will cause blotting. 6. Fully examine the connection of the contact points, ports and the wires as faulty connections can cause lighting problems. 7. Make certain that of the bulb does not come in contact with the interior light shield of the headlight when adjusting the bulb. colour:red Material:aluminum Package Content: 2 * High Power LED Lights Bulbs Only the above package content, other are not included.
