PY21W automotive light bulbs: type, uses, characteristics

PY21W are halogen and LED lamps used in vehicles. The letter P in the designation refers to the pear shape. Y indicates that the envelope is made of amber-coloured glass. 21W stands for output of the components in watts.

Where are they installed?

PY21W automotive light bulbs are installed in rear lights, brake lights and main turn indicators. They have a BAU15s base. The output is 21W and the voltage is 12V or 24V.

Characteristics

The halogen versions are characterised by the positioning of the tungsten filament holders, which are mounted at an angle to one another. These products are widely used in turn indicators of European car makes. Thanks to their multiple working elements, LED versions have high light intensity and turn on instantly, emitting uniform light. You should buy LED PY21W components if you want to make your car more visible on the road.

How to choose PY21W automotive bulbs

When selecting light bulbs, always check the car manufacturer’s recommendations and the specifications of the parts currently installed. Each lighting unit requires its own designated type. Installation of components that do not match the specifications of the factory-installed equipment is prohibited – this can cause damage to the light unit or result in a traffic penalty.
