These lights are a MUST BUY and will improve your SLK's look INSTANTLY!
Check out my pics! Installation literally took 10 mins to complete. The lights are plug and plays which made it super easy. You just snap the extensions on and plug the new lights right into them and BAM!!! There are a few wires that can be used but I didn't bother and I doubled checked to make sure both low and high beams worked and they did.
