Steam Cab Light On Peak Forest Locos

So, probably a dumb question, but is there some kind of light for the cabs on the Peak Forest Steam locomotives? The hotkey wasn't working and one of the timetables I was trying to run was pitch dark unless I opened the firebox.

Opening the firebox actually did work and was nice and atmospheric, but my helper kept closing it. Is there an electric light or a lantern or something on these?

 

There is a lamp on the left side of the tender, behind the driver's position

 

Thank you. Didn't have time to check during the in-game day as I had to go to work.
