Cornering fog lights / turning assistant.

Using Arduino Programming Questions
1

Can somebody help me to add another functionality to the code?
I would like to add an another / INT / and if there is a 5V /HIGH/ - both foglamps should go on.

What do you want an interrupt for?

Hants:
After changing RISING to INPUT - both lamps are on permanently..

I can't think of any place where it would be correct to use RISING where it would also be correct to use INPUT.

INPUT is not a proper mode parameter for attachInterrupt. However, it results in generating an interrupt request on the low level of the pin.

Any idea how to fix it?

Can I recommend you use the auto-format tool in the IDE before posting.
I'm getting travel-sick reading that.

No, certainly not - why?
