This is what happens when you copy and paste your post from the UK forum,it's the first click stop on the light switch over here we call them side lights,you in America call them parking/marker lights,when you put them on the radio,LCD's and the shifter lights up but my left hand heated seat switch doesn't but the LED bulb does.
I hope makes this clearer for you,so can I replace just the small bulb and leave the LED or do i need to replace the whole switch
