This item is a Pair of Brand New 5000K H4 100W 12V Super White Car Bulbs. These are halogen bulbs that are filled with Xenon gas to give extra brightness. The blue coating of the bulb eliminates the yellow effect to give a bright daylight white light.
The K rating is a NOT the level of heat or brightness but colour temperature. Our light bulbs has a K rating of 5000K, which gives the optimum HID blue tint effect.
Also, they consume the same power as standard bulbs and therefore would not get any hotter. They are also UV protected to use with plastic lenses. This item works on any cars based on the model of the head light socket.
The bulbs are design by the newest Japan "PALUTA" technology and absolutely incomparable with other short lived and low quality bulbs!
