Daytime Running Lights

Question by martindf24 posted 6 months 2 weeks ago in CLK-Class

I have been searching for the right bulbs to replace the daytime running light bulbs on my 07 clk550. Problem is I think I am calling them the wrong thing and I don't want to order the wrong thing. I do want to use LED though. I also am looking to replace the HID headlights. There is nothing wrong with them, I bought the car from a guy back in November so I just want peace of mind that the bulbs are new. ARe the headlights plug and play or is it more complicated than that? Request assistance Thanks in advance
