They were the same price for all 4000's were I purchased (Summit). The chrome models were more expensive though. The Hella wiring harness has the extra wire for the city light. This wire is connected to your positive wire for your side indicators. I believe Hella only offers the 4000 with the city light option on the Euro beam pattern only. Correct me if I am wrong. I checked Hella's website and the 74806 (black) and 74816 (chrome) in the Euro beam are the only ones with the city lights. If you need the information on the replacement bulbs for the lights, I can dig out.
