These are used and work as they should.  You have the option to set the sequential feature or not.  There were on the vehicle when I bought it, I am not a fan of the smoked lenses so I went back to the original red lenses.

**If you are unsure these will work on your vehicle or unsure what you are buying, please do not purchase.  I am not a business and cannot accept returns or provide refunds on electrical items.
