Led headlights installed. Dielectric grease?

Is it smart to add the dielectric grease to all the connections on the headlight? I noticed there was a good bit left in the brown connector from the stock headlights so i didnt add any more. Just curious should i add this stuff to each connection? (Sorry if dumb question, new to this sorta thing).

 

If water is a potential for introduction, yes throw some grease in there, it won't hurt at all and will protect that circuit for a long time.
Doesn't matter if it's LED or standard filament.

 

Yes, I put it on every exterior connection

 

Just pack it inside the connection?

 

I just dab all of the female connections.

 

I also use it on battery terminals. Primarily in the boat.

 

I consider it good preventative maintenance/cheap insurance.
