55W 6000K/8000K HID Xenon Super Light Kit Slim Conversion High/Low H4 H13 9004---Please tell us the Bulb Size and Color Temperature after your payment About Bulbs:1.Approved by accurate focus test Beam shape is the same as the original one, preventing glare when cars meet. 2.Base made of GE silicone from USA shockproof, heat-resistant ,no rupture even against heavy impact. 3.Anti-UV pure quartz bulb High rigidity, great light penetrability, heat and cold resistant,no implosion. 4.innovative buld design Preventing short circuit caused by touching the tip.Easy installation 5.Professional ceramic rod Professional ceramic rod made in Germany, noleaking or implosion. Easy startup no matter at high or low voltage profiting from the short distance between tube and rod. About Ballasts:1.Wide acceptable range of input voltage from 9~32V Applicable for almost all the auto Subject to specific model 2.SMR super microelectronic memorial chip Super capacity, can digitally parse and memorize different voltage and unstable electric current information, prevent interference fromother eiectronics,convert and stadilize the voltage after disposed by the ballast without interference to other electronics,which will bring a guaranteed performance and life-span of HID lamp 3.Pure aluminum casting lnsulative and never desquamates, on interference to the startup of air-condition, audlo and other electronic equipment on the auto. 4.Wide range of working temperature Work well even under the normal high temperature in the engine room, which can lessen the chance of malfunction caused by over heat. 5.Constant temperature protection Working temperature will not go up with longer lighting time. Even after2~8hours of lighting, it can still keep under 75,which complies with the international standard. About Wires:1.Approved by TUV lSO9001 Guaranteed quality.2.Excellent quality of heat resistant, fuel resistant and abrasion proof Made of the best wires and materials special for auto industry. Superior quality comparing with the one made by common material.3.Waterproof design Using the best waterproof connector, to prevent short circuit caused by electric leaking in water.4.Approved by computer cicuit test Ensure there is no short circuit or open circuit.5.Applicable even at high electric current (30A) Special design with low impedance, effectively slows down the aging of wires.
