This simple plastic single dome light with two-position on-off rocker switch has a snap out lens to make it easy to clean and change the bulb.  Wood grain trim matches many vintage trailer interiors.

Single light is 5-7/16"L x 5-7/16"W x 1-3/4"H.

Uses one 1141 bulb. 1.44 amps. 21 candlepower.

Very similar to the old Reflect-O-Lite 540.
