I checked with Optronics and the GLOLight Trailer Tail Light # STL111RB should have the same dimensions as the Peterson 421 light. It is 6-1/2 inches across and approximately 2-1/8 inches tall. Compare the measurements to your existing Peterson lights to confirm.

If the Peterson lights do not use a pigtail that plugs into the back of them then you will also need # A47PB.
