I was helping a some club members with turn stop lamp issues. I found corroded sockets and bulbs that had to be destroyed to remove them. I was surprised that nobody had heard of using dielectric grease.
Year ago I found the just a little smear of dielectric grease (GM called it silicon grease for use in their starter bushing) makes the bulbs go in very easy, prevents corrosion, and allows the bulbs to be removed easily.
Dielectric grease on the inside of the spark plug boots also ensures they can be removed easier when it's time to change the spark plugs.
Dielectric grease is not electrically conductive, but doesn't interfere with metal to metal contact electrical conduction.
Most auto parts stores carry it. BTW - it comes in small tubes and bigger cans and prices seem to vary a lot - so shop around.

Have used it for years and it works good!

Re: Dielectric Grease for sockets and plug wires.
I agree. I said much the same in a post earlier this month...

The voltage is applied but instead of current flowing to the bulb filaments, the high resistance in the corroded electrical contacts also generate heat, which ultimately melted the plastic connector shell.66corsaguy wrote:...Is there anything i can do to keep that from happening?

At this point, the badly deteriorated connector and switch need to be replaced. In the future, periodic inspection and cleaning will help to ensure proper operation and a good electrical circuit.
Also, try using this on metal connectors that are subject to conditions that promote corrosion. (Should help in the engine compartment multi-connectors, too!)

Re: Dielectric Grease for sockets and plug wires.
An old retired marine airframe & powerplant mechanic told me once that they ran out of dielectric grease on a Pacific island during WWII. He started using vasoline on all wire connectors on the corsair & p38's. It kept them from corroding in the hostile environment. I have used it ever since. I carry a small plastic bottle in my toolbox with a Q-tip stuck in it. I put it on all light bulbs and wire connectors. Works great.

Re: Dielectric Grease for sockets and plug wires.
In the vintage motorcycle community, if a socket or connector is corroded, soaking in vinegar removes corrosion, followed by dielectric grease to protect. I realize not everything can be immersed easily, but a zip lock bag filled with vinegar and rubber banded is possible sometimes.
