Dielectric Grease for Bulbs

Duration: 2:36

Having light bulbs or even LED light bulbs suddenly stop working on your classic car can be frustrating. Often the culprit is corrosion in the bulb sockets themselves. Turn signal lights, side marker lights, taillights, and even headlights can commonly fail due to corrosion. Stop these problems before they occur with the use of dielectric grease that keeps moisture and corrosion out.

    i like the idea of greasing the bulb but i noticed there was no mention of grease on the fingers and smearing the glass with it. when i install bulbs and high powered light bulbs i install them with a piece of toilet paper so i leave no oils and grease on the glass.

    You cannot have a Dielectric Grease that improves a connection. Dielectric means INSULATOR and it refers to the material used in Capacitors, Transformers and many other electrical or electronic devices where we need to separate conducting layers. In addition any grease even if its claimed to have some conductive properties will have poor conductive properties as some of the material is the “vehicle” that gives it the grease consistency. We need to have maximum conduction not have it limited by some pseudo magic . No one in their right mind would have a Starter Motor or Battery Cable made of some tube filled with a conductive grease. I can see an excellent use for it in coating certain connections after they have been made but normal neutral cure silicone would do that but is hard to remove so maybe this stuff is easier and wont cause any corrosion as it cures but the label says it is a silicone compound so best of luck getting it off. Silicone is a superb insulator as it stands heat, is flexible and the silicone leads on my soldering equipment make it a delight to use
