No, a light bulb does not involve a wedge. A light bulb typically consists of a glass bulb with a filament inside that emits light when electricity passes through it.
A lit light bulb is nonmechanical because it does not involve moving parts. When electricity flows through the filament, it heats up and produces light, but there is no mechanical process at work.
There are many items in everyday life that involve a wedge. A spatula for cooking is a wedge, a door stopper is a wedge used to stop the door, and a knife use to chop vegetables is a wedge.
The hypothesis of making a light bulb would involve proposing that passing electricity through a filament enclosed in a vacuum or inert gas-filled glass bulb will cause the filament to emit light due to the filament heating up and glowing. This hypothesis would need to be tested through experimentation to determine its validity.
A light bulb that uses a filament is also known as an incandescent light bulb.
Some inventions that involve physical changes include the light bulb (converting electrical energy into light), the refrigerator (changing the temperature to preserve food), and the microwave (using electromagnetic waves to heat food).

No.
Take out the two rubber grommets behind the light unit and use the flat blade of a screwdriver to press down the spring clips inside. Pull the unit out and replace the 18watt wedge-fitting bulb.

Knives, axes, scissors, and chisels. The forward edge of a crowbar is also a wedge.
Change the bulb. It uses a "wedge style" bulb. Pop off the red plastic cover on the right side of the lens (may have already fallen off). Loosen screw and pull out assembly. Twist bulb holder about 90 degrees to separate lens and holder. Pull bulb staight out.
Remove the two rubber grommets on the inside and, with a flat-blade screwdriver, flick the spring steel catches inside, so that the light unit pops out of its seat, exposing the 18Watt wedge fitting bulb.
Thomas Edison is best-known for the light bulb.
