These use addressable/chase led as default so the possibilities are endless depending on the controller. They can be made as RGB or single color. They are 5v LEDs, but don't worry I include the 12 to 5v converter. Trace hole location, drill .25" holes, run the bolts its that easy- the nuts for the lugs hold it all in place.
*Addressableor "chase" LED are what is seen in the photos. They have patterns that chase and display multiple colors at once
*RGBLED are standard multi color LED but the whole strip or block can only be one color at a time
