London Underground Passenger Light

Hello Guys,
How Can i activate the passenger Light on the Bakerloo Line Subway?
I pushed the Button multiple Times but the light is only on when i Take the Button, and then it’s always off again but it’s Never Stay on

 

Just confirming your using the button which is to the right hand side by the cab door? There's 2 red and 2 black buttons. Click the 1st red button. Hope this helps?

 

Where's the buttons to turn on the passenger lights

 

On the desk just to the right of the permanently-locked centre door. It's labelled something like "heat vent & light on". the other buttons turn these off
