Under Seat Music Synced Lights for Car (Updated)

This is an updated version of My under seat music LED lights. I originally used regular LEDs and the installation was not very clean. This version uses LED strips and the components are barely visible. The lights are very bright and installation is not very difficult. Please vote for me in the car audio challenge.

Parts required:

Car Adapter
TIP 31c transistor
LED Strip  (also order 3 extra connectors)
Wire
Solder
Audio splitter

Tools:

Soldering Iron
Velcro tape
Scissors
Wire stipper
