The advantages of LED lamp bulbs. 1. 200% more than the on-board halogen bulb. 2. Use pure white light for zero "warm-up" time. 3. Lower power consumption than halogen bulb, the energy-saving heating temperature is low, protect the car. The temperature of the xenon is about 800 to 1000, which is the main reason for the ignition of the car. 4. More than 30,000 hours of life. 5. Intelligent and efficient cooling system, built-in cooling fan, fast heat dissipation. 6. The mounting collar is adjustable for freely rotate, it's softly suitable for different light housing with different angles and easily adjust the light pattern, no blinding the upcoming traffic or divers. 7. New cooling system with a unique dual ball-bearing fan preventing the driving from the loud noise from the cooling fan, the all-in-one compact aluminum design brings better heat dissipation than common plastic design, and intelligent IC make sure the LED conversion kits last longer.
