This has come up on several automobile Forums that I follow. By definition, dielectric grease is an insulating compound so I can't figure out why it is recommended to apply it to contacts in order to improve conductivity. Clean the contacts and tighten them if possible by squeezing them together with a pair of needle nose pliers, insert the bulb, then apply the dielectric grease to keep the moisture out...
