I just wanted to know how to install them, (two for the C 240) underneath the engine cover / cap?! I was so eager when i got one of them in, and then i realized taht i needed two, so i got the second one but i can't figure out how to remove the cover. anyone help? Also, what are the bulb sizes for the fog lamps? 9006? or 9005 HB3 or something? How do you install those ones too!? thanks!
