Pls my skoda octavia fog lights are not working and they are new, what should I do?

Front or rear fog lights?

 

What do you mean by "new"?

 

Is the car new? Are the lights themselves new, or have you simply changed the bulbs?

 

Factory standard, or aftermarket?

 

Incandescent bulbs or LED?

 

To help you we need a lot more information.

Age and model of the car would help too. Is the bulb warning light on the dashboard lit?

Yes sir

 

Check for voltage at the lights.

Check fuse.

As mentioned more information will help.
