Running lights have been replaced twice with melting of the plug-in socket.To stop this from happening when replacing the bulbs use silicone to seal all the edges on the outer covering. Moisture inside the lights cause the bulbs to blow and the socket to melt. Seal around the light and no more problem.

My daytime running light was never work when I bought my truck used. I checked the sockets show signs of burning by the electrical contact but seems like nothing serious. I checked/tested both of the wires coming to the sockets and found that both of the wires are negative (-). (test every possible ways, couldn't find any positive(+) wire...so I just cutted the side that seems to be (+) and ran it to connect with the positive wire on the fog light. NOw whenever I turn on my fog lights the running light are also on. Don't what was cause or was it ran both negative wires from the factory.
