One of the orange lenses is cracked on my bike and I ordered a replacement set of the lenses. My question is how to replace the orange lense section as it seems to be bonded or glued to the black plastic base? I had assumed the replacements would come with the base attached, but I received just the orange lense section. Do I somehow cut the old lenses off of the base and try to bond the new ones on? What am I missing?
