I built a "Knight-Rider" (or Cylon if you prefer) style LED third brake light for one of my trucks. It is based on an Arduino Nano, though this would most likely work with an Uno as well.

Some Arduino programming and wiring knowledge is expected if you wish to build this project.

The Arduino "sketch" (code) is available here (UPDATED LINK):

In this folder you'll find a ZIP file containing a single folder with a single .ino file. No special libraries, headers or other dependencies are required.

Note that in my particular application, I added a toggle switch on pin A6 that disables the scanner portion, since I'm not sure how legal it is (I flip it when a cop gets behind me :) You'll see that reflected in the code.

The code itself is pretty self-explanatory, but does use multi-dimensional arrays and other things (I have been programming in C/C++ for many years so my style reflects that).

** Future Projects:

For my Silverado, I'm going to build a 12-volt version using Amber (yellow) LEDs on an LED strip. This way I can use it on the FRONT of the vehicle. I'll probably use 33 LEDs (3 for each of the 11 "modes"), along with a toggle to have them flash like warning indicators.

I may do another variation using RGB LEDs with an ESP-32, and an accompanying app that you control with your phone, with TONS of patterns, etc.

Many other projects are coming soon, so be sure to subscribe!

Be sure to check out the accompanying Music Video I produced for my other channel. It is a song and video parody of the TV show intro; all music performed by Justin Nelson:

Just a note that Glen A. Larson created the prop for BOTH the original Battlestar Galactica TV show and the Knight Rider show. Otherwise there is no link between the two shows.
