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

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.

Oh I totally believe everyone. Never investigated, just assumed they were aluminum.

I used to use petroleum jelly or dielectric grease on battery terminals to eliminate corrosion. Lately I have not been and don't see any corrosion, I assume due to the much better sealing of the batteries. I just replaced the 6-1/2 year old battery in my John Deere (which was actually vented but routed away from the battery) and had no corrosion on the terminals. The terminals had never been disconnected since installed at the factory.

I know I need to get more consistent on using grease on my trailer connections though.

Am I the only one who doesn't have troubles removing light bulbs? But then I don't tighten then with a pipe wrench

Angels watching over the innocent?

No, I don't have any trouble removing light bulbs either. I use my index finger and thumb to gently tighten them. I don't use any grease on the light bulb bases either. The only one I had trouble removing was a clearance light on a 100 foot radio tower. It was struck by lightning. When I got the glass globe off and looked for the bulb, I had a little trouble finding it. It was vaporized. What was left of the base was still in there but the glass bulb was now a thin film of silica on the inside of the glass outer globe. I managed to get the base out with the aid of pliers and the new bulb installed, but it was a pain.

I don't have any trouble with someone putting dielectric grease on the bulb threads and contacts, but I haven't needed to do that. I would certainly consider it in an outdoor or wet location. I have certainly used it on automotive bulbs. In fact I think a lot of them come that way from the factory.

Okay, we'll give you that one. :laughing:

Agreed! I use it on all automotive connections EXCEPT the battery terminals. I use a spray-on protector there, because it doesn't make a mess. If I DID use grease there, I would apply it AFTER tightening down the connections.
