In the 1981 C172P, there is a circuit breaker off the primary bus labelled "NAV LT" that goes to the navigation lights, control wheel map light, and audio muting relay. Here's the complete list of breakers: Primary Bus ----------- AIR COND CIR FAN - to air conditioning system or circulation fan system ALT FIELD - to master switch FLAP - to wing flap system PITOT HEAT - to pitot heat system INST - to ignition switch - to oil temperature gauge - to low-voltage warning light - to fuel quantity indicators and carburetor air temperature gauge INT LT - to door post map light - to dome and courtesy lights - to instrument, radio, magnetic compass, and post post lighting NAV LT - to audio muting relay - to navigation lights and control wheel map light BCN LT - to flashing beacon [cigar lighter has a direct connection to the primary bus] LAND LT - to taxi and landing lights STROBE AVN FAN - to strobe lights - to avionics cooling fan TURN COORD - to turn coordinator Avionics Bus ------------ [connected to primary bus through avionics master switch] RADIO 1 - to radio RADIO 2 - to radio RADIO 3 - to radio RADIO 4 - to radio or transponder and encoding altimeter RADIO 5 - to radio AUTO PILOT - to autopilot Note that many of the components, like the strobes, autopilot, and air conditioning, are optional extras.
