I dunno who invented these DRLs, because the lights on during the day was an intended campain to have people turn there headlights on during the day for the purpose of being seen, what people are doing now is turning fog lights into high wattage lights that are blinding to oncoming traffic, those lights in the bottom of the bumper are fog lights and are designed to face off to the side of the road to give more spread in low light and foggy conditions in conjunction with low beam in the headlights and contrary to the belief they need to be yellow, is not true, as long as they are not too bright, they can be any colour, google it if you don't believe me.
Our car has front and rear foglights and can only be turned on when the lights are on, the rears are a slightly brighter and different shade of red to the tail lights, the front fogs are a white light, slightly duller than the headlights and face off to the side of the road
Now factory DRLs are designed to come on when you start the car and go off when you turn your headlights on and not designed to be brighter than the headlights.
Save your money and just turn your headlights on, buy more beer, or if you have too cause you think the're coooool
don't turn them on at night with your headlights, think of oncoming traffic.
