The OSRAM LEDriving CANBUS CONTROL UNIT LEDCBCTRL102 is a 21W load resistor unit engineered to suppress dashboard error messages and prevent rapid-flash (hyper-flash) behaviour when fitting LED retrofit lamps in vehicles with CAN-Bus lamp failure detection. Rated at 21W, it is specifically designed for the higher-current circuits used in turn signals, brake lights, and reversing lights.

Supplied as a pack of two units with all necessary hardware, the LEDCBCTRL102 installs tool-free in minutes and is compatible with P21W, P21/5W, W21W and W21/5W LED retrofits.
