A question for all: When I bought bulbs a couple of years ago, they gave me some dielectric grease to put on the contact points (electrodes?) where the bulb and the power socket come together. I continue to use it, but don't know if it has any effect at all. I still am replacing the H7 Sylvania Silverstar Ultra bulb about every 12 months. Perhaps the grease does nothing?
The grease will do a few things, some that don't matter with the application...
- Prevents shorts due to water intrusion (not of use).
- Prevents the contacts from "welding" the connector together.
- Prevents "stiction" in the connector making the bulb easier to remove.
- Possibly assists in heat dispersion.
