Hey Russ, how many 172,s have you done ?
If only it were that simple.
Its very tight down there so unless you have Violinists hands, your going to have to be careful. Keep the first aid kit handy !
I didn't turn mine, I just pulled them and they came out. I just pulled on the wires and they came out easily.i found it easier removing the wiring before taking the bulb out , and its a quarter turn before pulling it
