What is the License Plate Light all about?

These are the light bulbs that illuminate your car’s front and rear license plates. Some cars have one per plate; others have two.

Traditionally, they have been incandescent; i.e., lit by heating the filament. These bulbs are inexpensive and provide good clean light. However, they die quickly and are highly inefficient, losing up to 90 percent of their power as heat.

Some studies suggest that LEDs, or light emitting diodes, provide drivers with safer night time illumination. An LED is a form of transistor that emits light when current is applied. LEDs are very insensitive to vibrations, have a long life, light up much quicker than incandescent bulbs, are extremely compact, run cool, and provide more light per supplied watt than incandescent light bulbs. Plus, they are high efficient. However, LEDs are more expensive.
