Hey Cheryl. I have a solution for you but your 20321-02 light has been discontinued and there's no replacement lens available for it. I recommend replacing your light with the Trailer Clearance or Side Marker Light w/ Reflector item # MC44RB.
The Trailer Clearance or Side Marker Light item # MC44RB has a red lens and measures 4" wide x 1-1/2" tall x 15/16" thick. It has mounting holes spaced 3" apart on center and uses a simple 2-wire power and ground installation method.
What kind of trailer do you have?
