The Royal Headlight Bulb 172562900 is a genuine 12-volt bayonet base bulb specifically engineered for Royal residential vacuum cleaners with headlight assemblies. This incandescent bulb provides bright illumination to help you see debris and dust while cleaning carpets and floors.

This replacement bulb features a standard two-contact bayonet base construction for secure mounting and reliable electrical connection. The durable glass envelope and tungsten filament are designed to withstand the vibration and movement typical of vacuum cleaner operation.

This headlight bulb is compatible with various Royal residential models that feature integrated headlight assemblies, including the Royal 4000 series and other models that use the HOO-1725629000 bulb specification. The 12-volt design ensures proper brightness without overloading the vacuum's electrical system.
