you will get check messages from the cold monitoring - you will need to turn off the cold monitoring... there is also a line in the programming for the LED tail lights that has not been tested by the forum members yet as to, what it does...

you can always get an LED light "bulb" and try it out, to see how you like it... bear in mind, the LCM is using PWM to control the brightness of the lights, and on the later models with BFD (brake force distribution) lights the LEDs can actually look as if they are strobbing... yours might not have the BFD, so you might be OK...
