H21W automotive light bulbs: type, uses, characteristics
H21W are single-filament halogen lamps. The letter H stands for halogen. 21W indicates the output in watts.
Where are they installed?
H21W automotive light bulbs are installed in turn indicators, rear fog lights, and reversing lights. They are not used in other lighting units. They are equipped with BAY9s bases. The output is 21W and the voltage is 12V or 24V.
Characteristics
A tungsten filament is mounted in the centre of an envelope, which is filled with a mixture of inert gas and a small amount of bromine or iodine. Quartz glass used in the production of halogen lamps can withstand high temperatures, which increases the longevity of these products.
You can buy H21W bulbs and other car products at attractive prices in our online shop. The range is not limited to parts for modern cars – here you will find spare parts for even rare or vintage vehicles.
How to choose H21W automotive bulbs
You should always go by the car manufacturer’s recommendations and the specifications of the parts currently installed in your car when choosing light bulbs. Keep in mind that each light requires its own specific type. Installation of components that don’t match the specifications of the standard equipment is prohibited – this can cause damage to the light and may result in a traffic penalty.
