I love the lights. The price was fantastic compared to other places online. The installation was a little difficult but thats due to mercedes. My suggestion is that the halo wires come pre spliced into the parking wires in the assembly. Also the parking light is a little bright so it makes the inside halo a little hard to see. I think i might just take the parking light bulbs out. Other than that the product is great.Bought these a little over a year ago. They looked fantastic, and worked quite well. Fast forward a year and 80% of the protective film on the lenses has peeled off. The lenses now have gotten cloudy, and look like they have 10 years of wear. Ridiculous.Paid to have the lights installed,after the shop took the fron bumper off ,took my headlights out , conected these headlight,they learned that they did not fit when puting the bumber back on. May have beed for a 4 door,and not a coupe.I need to return the headlight set. They do not fit a 2002 C230 sport coupe. OEM has two harnesses and lenses are shaped to comply with the front bumper. No instructions for LED application. Product looks good. I'm disappointed that it was not the right parts.This product does not fit 2002 Mercedes KOMPRESSOR, contrary to what advertisement say "This will fit you 2002 Mercedes"....Do not purchase these if you drive a 2004 c230 kompressor as it's advertised that would fit they don't. I finally got someone to install them trusting that the part would fit.Didn't fit like ad saiddid not fit....
