Headlights come on when I press brake pedal

Headlights come on when I press brake pedal
Hello, I hope I can be of assistance.
Can you confirm if it is the front side lights that come on or is it the dip beam? I assume it is both sides, is this correct?
Let me know and I'll reply as soon as I'm able to.
Thank you.

Have also just replaced blown brake bulb could it be the wrong bulb

Hello again,
does the blue main beam warning come on as well? Has this only happened since you swapped the stop lamp bulb?
Let me know.

No blue main beam has only happened since changing bulb

Hello again,
as it has only happened since you changed a stop lamp bulb this would suggest the incorrect bulb is fitted. On the Connect the stop lamp bulb is a double filament bulb and has 2 poles on it, if a single filament bulb was fitted when the stop light comes on this would create a short circuit to the lights causing them to come on.
Start with checking the bulb is the correct bulb, also just remove the bulb you fitted to see if the problem stops, if it does then you know there is a problem with the bulb.
Let me know if you have more questions regarding this and I'll reply as soon as I'm able to.
Best wishes,
