Car led shopping guide

Waterproof:

The car user had enough time to go the carwash to wash car at least once a week. the car led could’ve been an break, when user installed a poor quality car led. so the IP67 car led are still necessary.
Dissipate heat:

Every user know that , dissipate heat is import parameters for car led quality. bad heat dissipation is inefficient.heat sink (thermal conductivity of copper has good effectheat sink)is a good cooling solution. and thermal conductivity of copper is almost twice as much aluminum to heat evenly to the external heat sink. so the thermal conductivity of copper is best choose for car led.

Brightness:

The brightness are the important parameters. the car led should have lighting, some of warning(the led could act as a warning to other driver)each of these features. the led was so weak that it couldn’t warning to anyone.
