Led lights is not very common, why the car coat is so expensive
The car's lamp volume can be said to be fixed, but also to achieve such a large luminous flux, so that only the power of the LED to do up, because the unit volume of power is too large, making the LED heat problem is particularly difficult to solve, only With a good LED lamp beads and reflective cup, plus a good heat dissipation heat sink device. Because what materials are expensive, so make LED car lights particularly expensive.
LED is very common, the price of LED is much cheaper than before.
In order to save money ah!
