You could also install a few light strips around your board to make them standout even more. A good word of warning is that getting too carried away with adding lights to your board could mess with your vision a little bit when you’re throwing if you use the wrong color.

You can even install lights into the design of your board if you want to customize them a little further. Here is a cool video showing how you can build lights into your boards.
