What Size Hole Is Needed For Installation Of Optronics Flush Mount 4 Inch Round Light # STL23R-24B

Question:

I would like to install these flush mount tail lights and need to know the diameter of the hole. Will a 4 hole saw provided the needed holes size or does it need to be slightly larger? My application was previously surface mount lights but I am changing over to these recessed lights and need to know how big to make the hole since there are no installation instructions.

If you are using the Optronics Rubber Grommet for 4 Inch Round Trailer Tail Lights, part # A45GB, with the Optronics Sealed, 4 Inch Round LED Trailer Stop, Turn and Tail Light, Flush Mount, part # STL23R-24B, you will want to drill a 4-1/2 inch cutout. This grommet will allow you to flush mount 4 inch round lights to your trailer.

If you are needing the wiring for the light I have both a right angle pigtail and a straight pigtail available. The Optronics Right Angle 3-Wire Pigtail, part # A47PB, is the right angle pigtail and the Optronics Straight 3-Wire Pigtail, part # A45PB, is the straight pigtail.
