How do you turn off headlight

Your car has daytime running lights, meaning the lights come on no matter what position the toggle switch on the dash says (on or off.) There is a way to disable them (http://www.lightsout.org/disable.html#GMgen) but as a safety feature you probably would want to leave them on. A recent study suggests that you are 38% less likely to have a head on collision if you have your day time running lights enabled.
