Tungsten is a greyish white element commonly used in lamp filaments. It has a high melting point and can withstand the high temperatures generated when electricity passes through it, making it ideal for use in light bulbs.
Not wanting to state the obvious but the wall switch has to be turned on to supply voltage to the outlet. The lamp will need a three way light bulb in the lamp. A three way bulb uses two filaments of different lengths. One element is used for low brightness, the other filament for medium brightness and the high brightness setting uses both filaments in the bulb. If a single filament ordinary light bulb is used in place of a three way light bulb there will be a position on the three way lamp switch where the bulb will not light. Find the position on the lamp where the bulb will light and leave it there. Use the wall switch to turn the lamp off and on through the controlled receptacle.
Strontium was named by Humphry Davy (inventor of the mining safety lamp that bears his name) in 1808. He isolated the element by electolysis and named it after Strontian, a mining village in Scotland where it was first found.
A standard 1157 bulb has a 5 to 8 watt dim element and about a 21 watt bright element. An aftermarket 1157 LED bulb is between 3 an 5 watts total.
Glass tube: Acts as the main housing for the components. Phosphor coating: Converts UV light into visible light. Mercury vapor: Emits UV light when electrified. Electrodes: Provide the electrical connection to the lamp. Tungsten filaments: Heat up and emit electrons when electricity passes through them. Ballast: Regulates the electrical current flowing through the lamp.
A person who lives in a lamp is typically referred to as a "lamp dweller" or "lamp resident."

If you are asking about the electrical cord on a lamp, the black wire with the white stripe is the neutral conductor.
A 3-way lamp works by having a special socket that can accommodate a 3-way bulb with two filaments of different wattages. The lamp has a 3-way switch that allows you to turn on one filament for low brightness, the other filament for medium brightness, and both filaments for high brightness. This way, you can adjust the light output to three different levels by toggling the switch.
