If you mod the fog lights then who needs headlights..I dont.. Here is how its done..
1.remove the stock fogs from car.
2.stick the entire housing into a oven stitting at 300deg for about 10 min..
3.Take the housings out and carfully pry out the stock lens with a screwdriver while still hot(loosens glue).
4.After removal of the lens remove the reflector in the middle of the inside of the housing,Its only held on with 2 rivets.
5.reinstall the lens and seal it with hightemp silicone then get some 100watt bulbs..
Now you should have significantly brighter lights..If that is not bright enough for you then instead of putting in the stock lens's buy some 1/2" thick glass and have them cut to fit your housing(any window shop can cut them for you).. I did and also took out the headlights altogether and hard wired my fogs to the low beam harness just to make sure they wouldnt fry the stock fogs harness.. Here is some pics of mine..
This is my conversion..

Here is a closeup..

These are a side shot and a front of the brightness of 100watt halogen bulbs with the conversion..


This is the pattern that is given off by them..My Mom lives out in the boonies and these work just fine on dark backroad 2 lane highways..I only had a problem in a
HARD rain but it was becaes of rain not the lights..Wipers wouldnt go fast enough..

Let me know if you got anymore questions..
