These Tail Lights fit perfectly with the TJ Brutal Customs License Plate Bracket
To Wire to Your Honda Shadow from bike to light:
Green/Yellow to Blue (running light)
Green to Black (ground )
Brown to Red (brake light)
A tail light is kinda important so people don't slam into you when you are slowing down! Granted, a tail light doesn't remove the stupidity from the drivers around you, but it lets them know you plan on not going the same speed and may come to a complete stop. Basically, it's cool to not die by being rear-ended while on your bike.
