Some cars indicate this by turning on a bad bulb indicator. This problem can be solved with load resistor, and customer has to purchase load resistor seperately. (One Load Resistor is required for each bulb. Since the metal of the resistor will get a large amount of heat, please make sure your resistor is mounted on a surface that is heat resistant to prevent the chance of melting your parts.)***Please note: Some newer models of european cars or cars with canbus system may need to purchase the Canbus Error Free bulbs to bypass the on dash error message.
