Trivia: Incandescent and fluorescent are types of what?
Telephones
Lightbulbs

Cars
The correct answer is Lightbulbs
So why is this answer correct? : Incandescent lightbulbs have a thin tungsten filament inside a glass container and are considered the more traditional — albeit less-efficient — style of lightbulbs. Fluorescent lightbulbs use electrodes, gas containing argon, and mercury vapor to produce light, and are four to six times more efficient than incandescent bulbs.
