How to change a rh indicator bulb

Our reference doesn't list this, but most likely the bulb socket is cam-locked into the indicator housing from the rear. A quarter twist will release it. The bulb may also be cam-locked into the socket, or it may be a blade type that simply pulls out. Either way, hold the new bulb with a napkin or tissue to keep your skin acids and oils from deteriorating the glass of the bulb.
