well mine are on all the time as drl the same as my halo rings on the main lights. i also have hid fogs behind there so if the police say i'm running my fogs i can say no and turn the fogs on to prove it. also the fact i put a lense in there to aim the hids to down so there is no way they can dazzle. i hear all the people who think it's dumb to drive with fogs on and i agree with them thats why i did the halo rings and it passed the mot and the swedish mot is harder than the uk one for sure
