Should I Use Dielectric Grease When Replacing Bulbs?

Have some interior and exterior bulbs ordered; need to order a couple more pair. Then I am going to disconnect the battery and change a bunch of them over to LED. Should I get a 3oz tube of dielectric grease and apply a dap to the new led bulb connectors before I install? I thought it might reduce the chance of corrosion over the long haul; or is this overkill? Exterior only?

 

Wouldn’t be concerned with interior bulbs but if it makes you feel better on the exterior ones, go ahead. It’s not going to hurt anything.

Stock they don’t come with any and I’ve changed 4 year old exterior bulbs, and bulbs in the past that are lot older than that, that pull out easily with no corrosion.

 

I do it to all exterior connections. I’ve changed them all and added dozens more. Still working on the one small tube I’ve had and will probably last a few more vehicles.

not really needed for interior, but noted above, won’t hurt.

 

Short answer, it won’t hurt (usually)

But it also doesn’t hurt to understand how dielectric grease works.
It does NOT conduct electricity. Which makes using a SMALL amount on connections crucial to proper function.
Too much, and you risk actually making the connection weak.

If the connection uses a weather pack seal, I don’t usually use it on the actual bulb.
I apply it to the weather seal to help keep moister out. plus, it helps keep the seal in the connector from sticking if I have to remove it in the future.

If the connection doesn’t use a weather pack, I use a small amount on the connection terminals.
When I say small, I mean a skim coat. One small dab and smear it lightly.

 

Appreciate all the advice, I will get a small 3 oz tube (it is fairly inexpensive) and put only a thin coat on the connection terminals (thank TNShooter for detailing how dielectric grease works - I probably would have over applied.)
