There’s also the LED tail lights that come as part of the LED lighting group that do not house the sensor. I posted what I did, because I do not know if the LED tail lamps as part of the LED lighting package have the brackets internally to hold the BSM sensor. Obviously the halogen tail lamps won’t hold the sensor.There are two different types of tail lights:
Standard tail lights
LED tail lights --these come standard with the Safety Group and house the BSM sensors
I would think you would need the LED tail lights with the sensors if you wanted to add BSM later. Chances are you will also need the side mirrors with the built-in markers, and a flash by the dealer to activate the LEDs and the sensors.
