Allegro Bus fog lights won't turn off

I googled pics of a 2000 Allegro bus and it does not appear as if they had fog lights from the factory. Are they aftermarket? You could have a sticky relay. The air pump in my Allegro occasionally sticks "on" because of a sticky aftermarket relay. Once in a while I'll notice the air pressure getting higher and higher - well beyond the preset limit. I narrowed it down to the relay because it will run even with the key off. If I tap the relay it will shut off. I shut the circuit breaker off when I'm not around just in case....

Anyhow - hopefully you can trace the wires to a relay. There should be one if it's wired up properly.
