Tail lights

[stepsider]

When I bought my truck The PO had installed 4 " truck lights in the fenders. One of the lens was faded, So I wanted to change them out. With 4" holes I was Limted Went to O'reilly's & found 4" LED lights. Had to enlarge the holes to 4 1/2, came with rubber ring grommet. Had to cut the face of the grommet off
& put on the stainless trim rings that I got off ebay. Now the are flush mount. The old lights had a rubber ring around the light about 3/8 thick as you can see by the picture.
