ASH RECEIVER/CIGAR
LIGHTER LAMP UNIT
REMOVAL
An ash receiver/cigar lighter lamp unit is optional
equipment on this model (Fig. 1). The bulb and bulb
holder are secured by an integral mount to the out-
side of the cigar lighter halo ring, and serves to illu-
minate both the translucent halo ring and the ash
receiver. A small lens that is snap-fit into the inboard
side of the ash receiver bin allows light from the
lamp on the halo ring to also illuminate the ash
receiver. The ash receiver/cigar lighter lamp is ser-
viced only as a unit with the ash receiver housing
and cigar lighter receptacle. If the lamp is faulty or
damaged, the entire ash receiver housing and cigar
lighter receptacle unit must be replaced. (Refer to 23
- BODY/INSTRUMENT PANEL/ASH RECEIVER -
