asked by: Michael
Expert Reply:
The LED Trailer Tail Light # STL42RMB you're looking at has a lens with a 4" diameter but the hole needed to install it needs to have about a 4-1/4" to 4-1/2" diameter. This is the case with all of the 4" diameter lights though so you might end up needing to make the hole a little larger so you can install a light.
Please note that this has a plug at the back side of it so you'll need the 3-Wire Pigtail # A45PMB as well to connect this to your trailer wiring.
