The Monster Bluetooth Sound-Reactive LED Car Lights for the interior are a fun addition to any vehicle.  They plug in via the DC outlet and are simple to install since you just stick them up where ever you would like to have some fun lighting.  There are some cords attached, so I view this as a fun short term addition to the car but maybe not something that will be there fore years.  The app is simple to download and customize the lights so overall it is pretty straightforward to install these and use them.
