Just bought some aftermarket lights and need to remove the old ones, anyone out there know how?

 

What do you have? You might want to add basic info about your truck in your sig. Three bolts, two are easily visible when you open the hood, one above the other to the the inside of the headlight. One is under the parking lamp, just push down on the bumper and use a 1/4" dr 10mm socket with a long extension and it will rightfit in fine. Don't forget to remove the rubbber gasket near the two inside bolts and becareful when you disconnect the bulbs.
