You get them from super bright led. Comes in a spool I got 16 ft and cut
It in half then you just solder two new wires on the half you cut. You can cut them every 3" and there's new solder points. Then I pulled the plastic piece and kick panel and found the black wire with light blue trace that ran under the seat and tapped into it and grounded the other wire. Same wire on both sides. But there a common wire so if you open the driver door the passenger light comes on to. The LEDs have 3m sticky tape that holds them to the steps also.
