There are some cars that it look good under. Especially now that its not on every car out there.
I used to have blue ones under my truck.

Yeah had thee under mine, they were neons and one blew before I got it installed. They were used. So I had one short under the front, and two long ones under the doors. If I had kept the truck I was going to replace the 4th small one for the rear and I was going to but 2 mini's between the door and the rear wheel. It was a 98 ford ranger with flare bed. Looked pretty sweet. I used to deliver pizza in that truck and would turn them on when I was parked and delivering the pizza. It kinda got peooples attention so they didn't hit my car. Only time I got pulled over was when I accidently left them on. I had them hooked up to a remote switch which was uber cool, but was easy to forget when you had them on.
