go to pep boys and drop 20 bucks on clears... or bake em in your oven i think at 200 for 10 minutes, pull the lens off, take out the amber, and set the lens back on... but that is messy and time consuming, better off with the APC clear corners

edit: are you asking how to remove the whole piece or just the amber part? if you want to remove the light itself for whatever reason, there is a retainer screw at the top, you will see it, then it just slides forward. go gentle so you dont break the clip
