In Canada...well BC anyways...the MVA states that fog lights can only be on with low beams and that driving lights can only be on with high beams. However, in some autos (2000 Sunfire for example) changing fog lights to driving light is as simple as changing the bulb. The lights are supposed to be relayed into the corresponding switches. While I have no real desire to screw with my factory fog lights, my driving lights are hard wired so they go on whenever I want.BioMan said:Why is it that your not supposed to run around with fogs and brights on at the same time? Try as I might I can't think of a good reason that the fogs have to be off when the high beams come on.
