In Virginia during the winter? What does the temp drop to out there? Only
a
light bulb? Even with a thermal cover that sounds like lighting a room
with
a candle.

Bad analogy. Candles and similar concoctions have worked just fine to light
up rooms for thousands of years, and continue to work just fine for quite a
few people on the planet.

Ever put your hand on a hot light bulb? Given a nice cover, I would think
the bulb would do a great job of keeping the engine cozy during those long
winter nights....
