Do this with both wires. If the needle moves both times, then you have the right socket. If it doesn't: hold the red lead to one wire and the black lead to the other wire if the needle moves, you have the wrong socket.

If you have the right socket, put it in the truck and make sure you have a good ground connection with the socket. Use the meter to check it. Check the wires on the truck - there should be two of them feeding the socket. One carries power for the parking light and the other one power for the signal light.

Set the meter to 12 VDC. Turn on the running lights - first position on the headlight switch. Note that the parking light on the drivers side turns on. Touch one of the two wire ends coming from the truck wiring that with the red lead of the meter and the other lead to a good ground. If the needle moves that's the wire for the running lights. If not, do the same thing with the other wire it should move. Hook it up. Both parking lights should now be on. Then, turn off the parking lights, turn on the ignition, and turn on the right signal light. Touch the wire still unconnected with the red lead of the meter and the black to a good ground. The needle should pulse. if it does, hook it to the socket wire that's left.

Now, turn everything off except the ignition. Then turn on the parking lights go look at it to make sure both parking lights are on. Then turn on the right signal check it to see that it is flashing and is brighter than the parking light. If not, flip flop the two wires to the socket. Test it again. It should work.

If it doesn't come back and let us know what happened.

Either that or you haven't hooked up the lights as they were before and have the running light and signal light circuits crossed. AND it isn't going to do a bit of good to buy a new light fixture and install it - there's a very good chance that the new one you buy will be the wrong type as well. THERE'S MORE THAN ONE TYPE OF SOCKET AND THEOSE USED FOR JOINT PARKING AND SIGNAL LIGHTS ARE NOT STOCK. You need to identify the circuits and ensure the flow path is correct through the sockets and the wires.

Again, DO THIS!
