No. The light bulb is two words, not a combination of light and bulb.
Two
contact force:when two objects are in contact with each other it is called contact force.non-contact force:when two objects are not in contact with eachover
It's not the potato, but the electrodes you use to connect the lamp which must be different -e.g. a copper nail and an iron nail. The moisture in the potato acts as an electrolyte and metals chemically react with it, acquiring different charges (one becomes more negative than the other) and, hence, a potential difference is set up between the two electrodes. This potential difference may be high enough to cause a small lamp to glow. This will also work with lemons, oranges, etc.

Yes and no. If the peanuts are moist, not dried, they will act an electrolyte between two dissimilar metal electrodes - zinc and copper for instance - and form a cell that would power a low-volt lamp. The peanuts would be best if ground into a paste to ensure good contact and a continuous path between electrodes. The is also possible with something like a whole apple or potato as well, just push the electrodes in, but what is really powering the lamp are the chemical reactions at the electrodes.

You might want to try replacing the bulbs in the tail lights, could be a short in the bulb or possibly a bad ground connection You have installed a single contact bulb (possibly an 1156) into a brake light socket meant for a dual-contact bulb. The single contact bulb is shorting the two contacts in the dual-contact socket. The Fix: Replace the improper single-contact (single filament) bulb with the proper dual-contact (dual-filament) bulb. Dual filament bulbs are typically used in brake lights. Look there first.
