PlayStation How To Turn On Passengers Light On Isle Of Wight

Looking everywhere but i don't know how to light up passengers light on class 483

 

In the central car, there is a control panel on which there are buttons for controlling the light and doors.

 

It's in one of the passenger cars. There's a panel you can interact with that says passenger lights on and off. It is a little offset from where you press the button and the prompt appears

 

Find it! Thanks
