For a replacement light that is the same size as your ST70RBTK I have two options. One is the Optronics Trailer Tail Light - Stop, Turn, Tail - Submersible - Incandescent - Oval - Red Lens # ST70RB and the other is the Optronics LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 48 Diodes - Oval - Red Lens # STL70RB. The real difference here is sticking with an incandescent light or adding LED lights.

Both of these lights have the same measurement of the discontinued ST70RBTK which is 6-1/2" long x 2-1/4" tall. The LED has a slimmer profile at 1-1/8" thick when compared to the # ST70RB which is 2-3/8" thick. Both are recessed-mount lights so you will want a grommet like the # A70GB for installation.

If you would like to stick with a surface mount light the only option is one that is slightly larger or smaller than what you currently have. I recommend the GloLight LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 22 Diodes - Oval - Red Lens # STL178RFPB. This light is 7-1/2" wide x 3-5/16" tall x 1-1/8" deep overall and will mount to your trailer using the built in flange and 4 mounting screws which are not included.

I have attached some review and installation videos for your reference.

Based on the dimensions for the Truck Lite Model 60 that you have it matches the Optronics 10-LED Trailer Tail Light #STL72RB so this light will work as a replacement for you. The 48-LED version #STL70RB that you referenced is the same size and will…

Best option would be to connect the #A47PB to the wiring you have on your trailer currently so that you can easily plug in the GloLight LED Trailer Tail Light #STL178RFPB. For butt connectors you'd then want the part #DW05714. This is a really…
