ive seen foglights go on with the headlights going on. how do you do the wiring?

 

The fog lights only light up when the headlights are on, and they go off when you switch to your high beams. This bothers a lot of people who like to drive around all the time with only the fog lights on (they think that it looks cool).

There is another forum that is specific to Honda Jazz/Fits. In the "lighting" forum on that site are dozens of posts/threads about how to wire the fogs to work independently of the headlight switch.
