This works on spark plugs because the head is the ground circuit, but for a light bulb, positive and negative are right next to each other and if the grease bridges the gap, you have a short.
Dielectric grease is a non-conductive, it just seals out the bad stuff, so as long as each connection still gets mated correctly there won't be any problems.
