There are 2 thumb screws on each headlight assembly, remove these and it should come out.
There is a long bolt on top of the headlight/blinker assembly. Remove this bolt and slide the entire headlight/blinker assembly out just enough that you can see the bulb socket. Twist the socket and it will pop right out.

To change the low beam headlight on the 2001 Lesabre, the headlight assembly must first be removed from the car. It is really quite simple to do. There are two bolts on the top of the assembly that must be removed - that is all! The entire assembly comes out and gives easy access to the low beam bulb. Give it a 1/4 counterclockwise turn to remove it. Plus in the new one (#9006) and reverse the procedure.

I have a 1998 Buick LeSabre and to remove the headlights there are two screws on the front just to the inside of the high beam. Once you take these two screws out the headlight should slide towards the outside of the car and you can unplug the wire connector and you now have ht headlights off.
remove the 2 plastic screw knobs directly on top of headlight assembly, they will most likely be rusted in so you might have to use vice grips or channel locks to break them loose, after that the assembly will pull straight up and out.
