Well the the city lights which is what I did today all it takes is to replace the bulbs. I dont know for the DRLS since mine came stock with xenons. For the city lights took me like 5 min at the most.. here is 2 more pics at night. Sorry my phone camera has no flash
Very very easy mod to do just take of the headlight assembly open the back and yank out the day runners near the high beams and replace the bulbs. I can do it with my bare hands but some needle nose pliers helps.
