low beam headlights don't work

Its simple to first try replacing on of the head light bulbs and see if the low beam then works. Its easy to change the bulb. Red and a red/white wire bring power out to each of the low beams so that wire should be live when the low beams are on. They are protected by two 10 amp fuses in the fuse box and power comes through a light relay in the fuse box.
