Review on Carry-On Trailer 817-2 Marker Light: A Reliable Trailer Accessory by James Pfettscher

then this is what you need. It is manufactured by Carry-On and is a direct replacement. I give it four stars because it says exactly that. I took off a star because at this price a light body should last forever, but it doesn't. They rust inside after a few years. I thought since there is nothing more to say about this light I would like to talk a little bit about the replacement process. Let's start with the built-in splice connector, shown in blue in the picture. If you have a few inches of slack in the wires (which may or may not be depending on who plugged the trailer in), toss the blue thing. These connectors work by piercing the insulation of the source cable, which inevitably corrodes the cable and exposes it to air, moisture and contaminants such as salt. If you have a little slack, instead cut the brown wire where the connector was and strip half an inch of the insulation. If it's green or black and not shiny metal, then it's rusted. Cut it off another quarter of an inch and strip it again so that a quarter of an inch of the conductor is showing. It has to be clean. Next, use the built-in shrink connector. For the 18 gauge wire you probably have, it will be pink. Apply a small amount of corrosion resistant electrical grease to each side of the connector. Then put one brown wire in one end and the other brown wire and the black wire to the lightbulb, twisted together, in the other end. There will be enough room for both as the pink plug can be used for up to 16 gauge wire so there is some extra room. Of course, if you have a larger wire, use the larger integrated shrink connector. Terminals and shrink connectors to protect against moisture. Between the anti-corrosion grease you squirted in there and the shrink connector, you shouldn't have any more corrosion issues in that joint. Also apply anti-corrosion grease to the mounting screws, especially the back of the screw head. through the light of the earth. The mounting flange has a metal ring around this screw hole. This is a common point of failure for these lamps due to corrosion of the metal ring. Anti-corrosion grease helps prevent this. It's pretty much made for that. Then test the light to make sure it works. Please note that as the light is grounded via a mounting screw it needs to be installed in order to work. If it's dangling from the side of the trailer, it's not working. When the light works, carefully tuck the wires to make it nice and you're done.
