Last week, I had the dealer install the LED daytime running lights. The kit was in stock but the parts department had difficulty finding it since it was listed as a 2010 accessory. The service department had no knowledge about it. Therefore, I benefited from a mistake in the labor quote. They estimated 1 hr ($125) but literally screamed in horror when they saw the kit. When I picked it up they only charged me an hour labor but indicated future installations would be charged 5 hrs labor.
The lights look great and I am very pleased. My only minor disappointment is that the LED lights will not work with the headlights on. So you either get the daytime running lights or the headlights, not both.
The option is pricey at $550 + $125 for labor. I would have passed on this at $550 + $625 labor since over $1K is too much.
