I had noticed that my qtr panel marker light was not working. I have had a few bulbs replaced in the same light over the last 4 years. I had installed a set of Diode Dynamics LED bulbs. I had some extras and I went to replace the bulb and was shocked to see the plastic housing had apparently been filled with water and now has rusted out the entire socket. I new socket assembly is now needed. Like Roseanne Roseanne Addanna use to say......"It's always sumpthin'. "
