Yes, I had a problem with the Bargeman/ Standard RV conversion. As a former HVAC mechanic, I am very adapt at using a Fluke Digital Meter. While replacing the
tail lights. Someone replaced the right tail
light before and it was always dull compared to the left one. I had to switch the green and brown wires. On RV Standard the brown was listed as tail
light and clearance (side)
lights but on the Bargeman it is green. I just replaced the old LED ones for a waterproof Marine set from Amazon. The Fluke is polarized sensitive and will tell you if the polarity is reversed. It is hard when you are working with LED because you can't get a resistance reading like you can with a bulb. Thanks' for the reply
