Gary, do you mean wiring the controller into the fog lights so when the fog lights are on the DRLs go out ? If so you'll also have to wire it so when your headlights are on the DRLs go off to meet the lighting regs.Just wondering about wiring a DRL controller into the front fog lights & disconnecting them as fog lights can't think of a situation where I've ever needed them.
what are the legal implications?, don't think front fogs are tested as part of the MOT @t-tony
Could even put some brighter LED bulbs in
