NOTICE IN AUTO LED BULB : DASH BOARD ERROR MESSAGE-- Please be advice that many modern luxury cars which computer built in such as Mercedes Benz, BMW,. etc., have sensors built into the dashboard computer system that can detect if light bulb works. However the purpose to use LED BULB is energy saving, which means the car computer will misjudge the LED BULB not work because of the low wattage to lead the error signal showed in your dashboard.
