These lights go on the bottom of the door and when you open the door up at night, they light up and display the Maserati Logo on the ground. Pretty cool option for your car. Sold as a pair so if you have a 4 door you will need 2 sets. These measure approximately 2.75” x 1”, I have had people say these did not quite fit the opening in their door. In this case you may need to use double side tape to install since they may not click into place
