It's rather easy, and if you want the Right (drivers side) headlight can be accessed without removing the whole headlight assembly,,, if you reach down and twist the light counter-clockwise you can remove it and then pull back the red tab and replace with a Silverstar.
As for the Left (passenger side) you'll need a 10mm with an extender. There are 3 bolts in total. After you pop the hood you'll see a Black plate just to the right of the headlight assembly and there will be two Bolts there,, remove those. Then down by the tire you'll see a "plastic plug" in the wheel well, remove that and you'll be able to see the last bolt,, it's very tricky and you will most likely drop it..

it can be a pain in the a.. but with some patience it's easy.
Now for the hard part,,, the assembly is a pain to remove. I found that a good hard pull on the top left corner (top right for the drivers headlight) usually gets it out. It has two plastic "guides" that always like to catch but like i said a good hard pull on the top corner will get it loose.
Hope this helps!
