CAN Bus LED Bulbs – FAQ
What does CAN Bus mean?
CAN Bus means Controller Area Network Bus. This system monitors your vehicle and reports operating conditions. CAN Bus systems are commonly found in European vehicles such as BMW, Audi, Mercedes, Volkswagen, Porsche, and in many American vehicles. While most late model American vehicles have CAN Bus systems, it is always good to check with your vehicle dealer to see which system your vehicle has before purchasing electrical products.
Will CAN Bus LED Bulbs Prevent “Bulb-Out” Indication?
Each vehicle has different requirements that the CAN Bus system is looking for, but in most cases CAN Bus LED bulbs should prevent a “bulb out” indication in areas such as tail, brake, and running lights. If you use a standard LED bulb that is not a CAN Bus application, you would consistently get a “bulb out” dashboard indicator because your system can’t communicate with a standard LED bulb.
Will CAN Bus LED Bulbs Prevent Hyper-Flashing?
CAN Bus bulbs will not prevent hyper-flashing of turn signals. These bulbs are communicating with the CAN Bus system, but the relay still needs an appropriate amount of load to operate correctly. Your electrical system could require load resistors or an electronic flashing relay to stop hyper-flashing. The factory relay causes the hyper-flash when it thinks there is not a bulb working.
