Vintage hospital “Engaged & Enter” sign. 
This can be switched off so that no lights are lit, or each word can be lit independently. 
The ENGAGED sign is lit in red for stop and the ENTER sign in green for go! 
The box surround is the original teak and hasn’t been restored, showing the patina from its life and use. 
It has been rewired and re-lit in LED lights so it doesn’t get hot and is very inexpensive to run. 
Measurements: 30 x 11 x 20cm high.
