  Hey Mike, we don't carry the light you referenced but it looks like it's a 4 inch round LED trailer light similar to the Optronics part # STL55RB. Would this work for you? For a grommet you'd need the part # A45GB and then for a wiring harness part # A47PB.

• Recommended Trailer Tail Lights for 4.25 Inch Opening
  The LED Trailer Tail Light # STL42RMB has screw mounting holes that are 4-1/4 inches on center. The smallest hole this light will fit is 4 inches. You will have difficulty mounting this light as your opening matches the mounting hole locations so you won't get proper hold. You may want to use the Rubber Grommet for 4" Round Trailer Tail Lights # A45GB along with the # STL55RB which won't use any screws to mount. You will also want the 3 wire pigtail # A45PB.

• Recommended LED Replacement Lights for 2005 Damon Daybreak Motorhome with Load Resistors
  The Sealed, 4" Round, LED Stop/Turn/Tail light, 21 Diode - Red # STL55RB will work great on your motorhome. You will simply need to use the wiring pigtail # A47PB for each light.

• Can Trailer Taillight STL55RB Replace Incandescent Bulb on Older Vehicle
  If you wanted to install the # STL55RB in place of the bulb you have now on your vehicle you certainly could but there isn't a direct adapter available.

  Both the Rubber Grommet # A45GB and the Notched Rubber Grommet # A45GNB that you referenced will fit and work well with the Optronics 4" Round LED Light # STL55RB. The only difference between the two grommets, as you mentioned, is the notched cut out in the lower portion of the unit. This is not necessary for wiring or fitment, but it will allow for a bit of an easier install.
