Probably An RV Lamp
DUAL SWIVEL AUTO READING LAMPS
This 7” x 4” x 1-1/2” 12VDC interior incandescent light probably came from an RV, but as we like to say around here, use it as you see fit. Black outer housing contains (2) 2” x 2-1/2” white reflector swivel heads, has (5) mounting holes and connects via (3) spade terminals. Connect (2) of them and both lights will light up and turn off when tilted. Run a jumper from the positive terminal to the AUX positive terminal to get it lit in all positions. That’s fun.
