Yes they can produce electricity when two different metals are used as electrodes. Though it can take quite a few to light an LED light bulb. But with a Christmas light no for some reason it does not work.
yes

No, unless you hook it up electronically then it will probably not produce enough energy to light it up as bright or as long as and outlet.
yes of course
Matter can travel at any speed you like, if you can pump enough energy into it.The only limit is the speed of light. If you can supply it with enough energy, thenyou can make the matter move as close to the speed of light as you want it to,but there is not enough energy anywhere to make it move at the speed of light.
light energy is not strong enough! <--NovaNet
The citrus inside of it.
Any producer of heat can produce light by reaching enough energy
Matter vibrates because of the application of energy. If the energy applied is enough, and an electron is smashed out of its orbit, you will get light.
Excite electrons

Yes you can.
