Bulbs H9

H9 automotive light bulbs: type, uses, characteristics

H9 is a halogen lamp, which is indicated by the letter H. Xenon (HID) and LED versions, which are available as replacements for the standard halogen ones, are also marked with the same designation by automotive parts manufacturers.

Where are they installed?

H9 automotive light bulbs are installed in headlight assemblies and fog lights. They serve as headlights and are used in foggy weather. They are not used in other lighting units. They are equipped with a PGJ19-5 base. Their output is 65W and voltage is 12V.

Characteristics

These components can be used in ultra compact headlights, at the same time ensuring an intense light beam. It’s worth noting that halogen versions can be used as well as xenon (HID) ones. The former are equipped with a glowing element mounted in an envelope filled with inert gas. They also have a shield that cuts off the low beam light. Xenon (HID) versions differ by the presence of electrodes mounted in a gas-filled envelope, between which an electric arc is formed during operation. The working element of LEDs is a number of diodes that imitate a filament in form and location. Ultra low energy consumption is the best reason to buy H9 LED lamps, if the vehicle manufacturer allows such replacement.

How to choose H9 automotive bulbs

When selecting light bulbs, always check the car manufacturer’s recommendations and the specifications of the parts already installed. Each light has its own designated type. Installing components with specifications that don’t match those of the factory-installed equipment is prohibited – doing this can damage the lighting unit or result in a fine.
