Class 377 Instrument Light Switch

Hi All,
Does anyone know where the dimmer or On/Off switch is for the instrument panel lights on the above train?
Trying to avoid use of keyboard where possible so the location in cab would be ideal.
Thanks

 

I'm sure you can't either dim them or turn them off on either variant, same with the other Electrostar variants in game I'm afraid

If anyone knows more, be sure to correct me if I'm wrong

 

Ahh ok, thanks for responding anyway. It all adds to the knowledge bank

 

No worries
