What Bulb For License Plate?

When it comes to selecting the right bulb for your license plate, it might seem like a trivial decision. However, the license plate bulb plays a crucial role in ensuring your vehicle remains legal and visible, especially during nighttime driving. 

With various options available in the market, it’s essential to understand the different types of bulbs, their specifications, and factors to consider before making a choice.

Types of License Plate Bulbs

There are primarily three types of bulbs commonly used for license plates:

Incandescent Bulbs

  • Traditional incandescent bulbs have been a standard choice for license plate illumination for many years.
  • They produce light by heating a filament wire until it glows, emitting a warm and familiar light.

Halogen Bulbs

  • Halogen bulbs are an improved version of incandescent bulbs, offering higher efficiency and longer lifespan.
  • They contain a halogen gas that enhances the efficiency of the filament, resulting in brighter light output.

LED Bulbs

  •  LED (Light Emitting Diode) bulbs have gained popularity due to their energy efficiency, longevity, and compact size.
  • They produce light by passing an electric current through a semiconductor material, emitting bright and crisp illumination.
