My dealer charges $650 to install the driving lamps! ARGHHH!
You need some basic mechanical skills to install auxillary lamps. I would not suggest such a project to someone with minimal mechanical skill. Wiring the loom into the high beam switch (which must be done), fishing the wires under the dash and through the engine bay, and installing relays on both lamp circuits (also must be done unless you want to take a chance on frying your wiring = no warranty coverage) isn't the easiest project I've seen.
I've installed them on other cars, with relays, it takes a little know-how.
If you can work on cars a bit, do it yourself. There's plenty of info on the web about this, but again, it's not a project for the uninitiated.
My 2c worth, I hope it's helpful.
