Is there any issue with using vaseline around the threads on a light bulb to prevent corrosion. I know it might increase resistance but not by much?
 
Thats a good question, I have done it before. But never really gave it much thought. I'm sure some of the others will have an answer for this.
 
Number one answer= what does the manufacturers specs say about it ?
 
Most of the corrosion problems are due to lamps with aluminum bases. The lamps we use in traffic signals have brass bases and are rated 8,000 hours.
But don't know about the vasoline....
 
if this is a screw in base, what is to stop the vaseline from causing a continous path from line to neutral if the vaseline truly is conductive?
 
I have been using Bulbez for five or six years. It works pretty well. Most supply houses around here (Chicago) do not carry it. You can get it from McMaster-Carr.

As for George's question, vaseline is a hydrocarbon and somewhat combustible. The MSDS for petroleum jelly lists flammability as a risk and mentions that it can be ignited by sparks. It also provides the flash point as 199C or 390F. All in all, sounds like it shouldn't be used around electrical equipment.

Campers and hikers use cotton balls impregnated with vasoline as firestarters. They ignite easily and burn quite hot.
