Actually, the light protection kits you could easily do yourself. Quite different from their Paint Protection Kits... these are 80mil (VERY thick), but hardly noticeable since they go right up to the edges.
The install procedure is rather simple. You clean your headlamp like Bijou mentioned, then turn on your headlights until the front lens is warm (don't get fingerprints on), then work from the center out. They provide you w/ a squeege. Again be sure not to touch the sticky side or you'll get finger prints on it.
