Put a dab of dielectric grease on the bottom of light bulbs.

Yea tinned copper

So what product is the green/yellow grease you often find on OEM stuff the first time you change a bulb

Doesn't that suck..... Why hasn't someone came up with some good, easy to use copper connectors??

All of the automotive butt connectors I have are a plated copper alloy. They are not aluminum. I think the plating is likely cadmium.

I read thru some of the other posters in this same vein, and yes the plating is probably Tin and not cadmium. In any case I am not sure what the plating is, but the body of the crimp connector is copper, that much I am sure of.

I don't think I've ever seen an aluminum butt connector. Prob cuz I never work with Aluminum wires. What electrical item are you working on, that has Aluminum wires? Incidentally if you are working with aluminum wire you MUST use aluminum connections, butt splices for example. Or if you MUST join your aluminum wires to copper, you have to use the proper goops for dissimilar metals. It's not ideal.

I'm assuming you misquoted in regards to never having saw an aluminum butt connector? What kind have you saw?

James, where do you get copper connectors?

Okay, I'm slow..... guessing my crimp connectors are also tinned copper.... sorry for the doubting.... thanks guys...

Re: Put a dab of dialectric grease on the bottom of light bulbs.

Heating and breaker tripping of an induction motor under load is real, but the "poor connection" causing over heating of a resistance load is flawed.
That is not how it works. In fact, the poor connection acts as an additional resistance "heater" in series with the load.
E=I^2R Tells the entire story.

And then to make a short story longer......
The Great Lightbulb Conspiracy - IEEE Spectrum

I think we are saying the same thing but I don't think I said it very well. If there is a loose connection (poor connection caused by oxidation) it means that there can be poor electrical contact. This means that there is resistance to the electric current flow causing power to be dissipated as heat.

Don't take our word for it, take off the plastic and take your pocket knife, and scrape it, and you will see the copper.

How long will my "10 year" LED bulbs last if I do this?

Who cares? When they burn out take them back for a refund.

I spray just a very little bit of WD-40 on the bulb threads of the first bulb to go in. After that they almost all screw in easily. How long they last? I doubt it makes any difference, but I always buy the long life bulbs anyway.
