Hi, welcome to Just Answer. My name is***** dash lights and ashtray get power from circuit K from the headlight switch. If you have no power to the ashtray light with the headlights on I'd say you have a bad headlight switch. Copy and paste the link below for a schematic of the circuit. S1 is the headlight switch. R2e1 is the ashtray light and terminal 13 at A1 is the feed to the instrument panel rheostat.
