Note on replacing outside electrics
Not as big a deal out here in the dusty SW, but you folks that live where that mysterious water from the sky thing happens may want to invest in a tube of "dielectric tune-up grease" for marker lights and such. A little bit on the contacts and base will have 2 positive effects.
1. Weatherproofing to some degree against rain and condensation.
2. Keeps the bulb from "freezing" in the socket, and thus being well-nigh impossible to remove.
I've been putting a light (very, very little) coat on marker lights, headlight electrical prongs, etc. on my various vehicles for many years, and its a cheap insurance policy against having to replace something by the side of the road somewhere.
**Note: Do *not* get grease on the glass part of the bulb. Bad things happen.**
