Actually a REEAALLLY good way to do it:
Take a soldering iron and burn a * shaped star grooce on the plastic amber piece. And then take a screw driver and a light hammer or mallot, and punch it with the screw driver, and the amber piece will shatter into little pieces, then you just have to flip the headlight and let all the pieces fall out, if some piece gets stuck, use a needle nose and break it into smaller pieces and pull it out. and ur clear tailz are dunn!!
