the interior light switch is the button that you turn your headlights on with, you have to pull it out to turn it on
The light is on because there is a fault somewher. To turn the light of you fix the fault.

Push the main light switch to bring on, push again to turn off

Hi turn the wheels on full lock there is a flap in the wheel arch you access the head light bulbs there.
Because it is British.
Get in car. Put key in ignition switch. Turn key.
its probably something to do with the wiring system
Twist the knob on the right side of the steering wheel to the right,
You will also have no interior light. When the Astra has a accident and it deployes the airbags it turn on the hazzards and interior light. You will need a new airbag module which is under the centre console. If your lucky it might reset using the vauxhall tech 11 but this is a dealer tool a good auto electrian will be able to plug in the vehicle and reset or diagnose the module failing that its a trip to the dealer. Check the seatbelt holders on seat see if there ok they should be quite long and easy to plug in the belt if there short and the stems look quite wrinkled they have been deployed and want changing to..
It will need to go on a diagnostic machine to have the codes re set, and any faults would need to be corrected before the light would extinguish
