Doug,

None of the machinery standards require lighting in the panel, they simply 
permit it where the designer wants to use it, and provide rules for the 
installation should you choose to install it. A risk assessment should be the 
deciding factor, and any customer preferences for the provision of lighting. 
Have a look at the questionnaire provided in the Annexes to IEC 60204-1 for 
development of the electrical system specification - I think you’ll get the 
idea.
