Re: LED tail lights
jim, the only purpose of a resistor is to resist the amount of power it passes through to another part of the circuit.. if you think of a toaster, all those coils that you see inside are a form of resistor (not literally, but figuratively) and when electricity passes through them there is resistance to the path and it produces the heat you see, and hence it toasts whatever is in the appliance. an electrical resistor performs the same function. it has full power leading up to it but resists it and passes through a reduced level of power. LED bulbs require significantly lower power to operate but the canbus system in the crossfire is looking for a full power response or it triggers the lamp out indicator. that is an over simplification, but is gives you an idea as to how it works and why in the crossfire it is needed. i will be installing these bulbs in my srt6 crossfire roadster. my corvette is all led from interior, headlamps to led halo sequential tail lights. never had a problem with even 1 bulb on the vette. i purchased canbus red led taillight bulbs that come up when you enter the vehicle information on that website. the bulb (part) number is 1157-R30-CBT-2PK: Red - 2 Pack. this is from their site:
Note: Newer vehicle electrical systems may require a CAN Bus bulb for operation.
