**NOTE** Some may notice I neglected to include a resister. I had plan to place it elsewhere in the harness, but I may just integrate it into the signal housing later (recommended). I also recommend using something more durable than cardboard to secure the LED in the signal's socket (step 9). I just use it because it was what I had on hand at the time; I'll be changing that later, too.
**ALSO** This is my first instructable, so if something is out of place, forgive me.
