BA15S Resistance

A power resistor that helps the car's light monitoring system (Canbus) to detect the presence of an LED lamp instead of a halogen. Since an LED lamp requires much less power than a classic halogen, an extra resistor may be needed to prevent the Canbus system from thinking that the lamp is broken. This is a splice that is fitted to the existing lamp holder and then attached to the reflector. It's plug and play and you don't have to cut any wires to plug it in.
