Carolyn, is this for a Clamshell, or inside kitchen. I've searched forever to find the same size replacement for the Bargman lights in LED and can't find anything the same size. I have put LED bulbs in mine, but not really satisfied.
In the case of the bulbs for inside kitchen Dutchmen T@Bs, I think there is a circle LED bulb that will fit, but don't know the specifics. I'm thinking Crystal Baker may have done that.
do you mean the wiring harness or just the taillight?
these tail light replacements are pretty close in size some minor adjustments(wiring and minor modifications to the assembly) would be needed but would provide the LED/Brightness you are looking for? unless we can find a 3.75 inch lens (so far all i am finding are 4 inch or bigger)
