I bought two clear side marker lenses to replace the amber ones on my C2. The owners manual explains how to remove the lens cover to change the bulb. I am having problems! I can not seem to get the spring clip to release with a screw driver. Has anyone else done this themselves? What is the trick?

As an aside, the new clear side marker lenses came with orange bulbs in them. Is it proper protocol to leave the orange bulb or replace that with clear as well?

Thanks!
