Interesting story about the lack of heat generated by LED bulbs in traffic lights causing the lights to be covered by snow and ice. http://denver.cbslocal.com/2017/11/07/led-traffic-lights-consequences/?utm_campaign=true_anthem&utm_content=5a02b27e3ed3f000074f8ff3&utm_medium=facebook&utm_source=social

I have always been accustom to putting a 100watt incandescent bulb in the oven to keep food warm and heat up leftovers (redneck microwave).
They are getting hard to find.

That sounds like a race between "warm enough to eat" and "food poisoning."

The carpenters I worked with, their first order of business was to build and set up their construction hut.
Made a 2ft by 2ft box lined with Foil-Faced Foam Sheathing board and a light socket with an industrial 250w incandescent light bulb.
That was their oven, it would cook most anything and heat things up safely in a work environment without a flame.
A 100w incandescent light bulb will create some serious heat, enough to keep food warm.

A Harris, welders used to keep an old refrigerator (door locks removed) with a 100 watt bulb installed to keep welding rods warm and dry. It worked pretty well for warming up leftovers for lunch too. That is if we didn't have an air compressor nearby where we could use the exhaust manifold.

Keeping food warm (as opposed to hot) is a welcome mat for bacteria. If it works for you, go for it!

I had a crew member that use to heat up cans of various "lunch goods" on the exhaust of the truck once we got to a job site. It was usually something like corned beef hash or pork & beans. One day the big boss dropped by and grabbed a couple of my hands to take to another site and this fella was one of them. In the hub-bub he failed to let me know there was a can of chili beans nestled under the hood by the exhaust.

The can did not suffer structural failure until I was on the highway on the way home that evening. I heard a thump and smelled burning chili beans. I immediately knew what had happened.

Every time I would check the oil I could still smell those damned burned beans.

Ya know LED lights do generate heat and they have a heat sink built into them but I doubt it is sufficient enough to keep snow or ice off of it.

I cooked many a can of C rations like that on the manifold of a 5/4 ton truck. You had to remember to vent the can first to avoid a similar situation.

I once had a book of recipes for preparing food on a hot engine. It was full of directions like "...after applying the marinade, wrap the steak in foil, attach to manifold, and cook for 30 miles." The book's title was "Manifold Destiny."
