Think the are both different ones, but double check first on the passenger side of the dash. Yep, bumper removal jobbie. There is a guide on here if you don't know how to do it. archlines either side then bolt under the arch liner, then the grill and a few more under the bumper. but can be done without doing the lower ones. Each headlight unit has 3 bolts as well.
When changing the ballast make sure you have the correct torx driver T15 or T20 i think and simply swap them and check they work/dont work before putting the bumper back on.
