I'm confused is the issue with the front DRLS and is there was there an issue with the rear side lights ? And was the light you tapped a rear one with a fault at the rear?
Try this with the key out, turn on the lights, now check all the side lights front(dim) and rear.
Turn them off, start the engine, are both bright drls on? This is not a fix it's just to confirm what's working and not?
