Canadian cars come standard with DRLs (law since '89) and usually it's the highbeams on reduced power. My car's in the shop at the moment 'cause I got rear-ended by an X5 two days ago, so I can't just walk out and check--is it the same for the Focus? If not, I may ask my buddy to see if he can rewire the fogs to just always be on whenever the car's running.
No it's not, Focus mk3 uses DRL on low beams, at a reduced voltage (9 volt)...
Easiest way for me was to add a relay harness + resistor... I did wire a switch on my relay harness that goes to the interior of my car, like this I can close ALL lights, and all power is sent to my resistors. When i open this switch, i get my low beams (HID). I never get bulb out error cause of resistor, and i can control my lights like I want (only low beams, only fogs, or both). It's my way of by-passing those DRL
