How do I change a low beam head light in a 2001 jeep grand cherokee?

I took out the battery but I could not get to the bulb.|||this is actually very easy. open up the hood, there will be one long screw that you take out, then just pull on the entire unit, it will pop out, but it does take a little force since there are these ball joint type pieces (kinda hard to describe) that hold it in. Once you get the unit out, just unclip the wires from the bulb, then take out the old bulb, put in the new one, hook it back up and put it back in. Should take about 10 minutes.|||on a jeep you would have o open the hood and go from the inside then undo some srews then the lights shouldscrew right in|||you actually have to remove the screws and the whole headlight housing comes right out ..
