Haha! Sorry, been crazy busy lately. I actually have not done anything with this project since I first posted it.
steved0x was kind enough to donate a set of ambers to the cause, so I will go at them soon and post a DIY and show the finished product
You could do it with sandpaper, but it would take a long time. The Dremel goes pretty darn quick, but could cause some serious damage to the headlight or your person if you're not extremely careful.
