My front headlamp burned out in my LS. I wanted to avoid the dealer at all costs. Currently living in a colder climate, I also wasn't enthused about the prospect of trying to figure out how to change the bulb when it's freezing outside. I bought a new pair of bulbs from theretrofitsource.com so I could get both replaced. I contacted a local body shop to see if they could do the swap. I figured since they work with assembling and disassembling car body parts they could probably do the job faster. They said it took less than an hour to do both, and I paid 50 bucks in labor. This was an independent body shop so, I'm not sure if this is realistic to expect at all body shops but, I'm not sure if I could have gotten it done cheaper any other way (besides doing it myself). So, if you're in a similar position as me, consider having a body shop do the swap. For me, I'm more than happy spending the 50 for that.

 

Many here at CL have used Retrofitsource for their bulb replacement, including me. They're priced right and the quality of their products are great.
