The LS348 or KD522 marker light was used on 1975 to 1978 Airstreams and on a few other vehicles in the 1970s.

This is a complete assembly that includes the base, bulbs and lens. This is the entire assembly produced by high quality injection molding. It's really nice to be able to faithfully replace the entire 40-year old unit. Red lens is not sold separately.

The lens measures approximately 3.75" long and 2" wide. It fits in a rectangular base in the taillight array.

Comes with one complete assembly with two bulbs and one lead wire. Grounds through mounting screw.
