I believe the light and reflector color matter, by law.
The clear corners that I have don't have amber reflectors on the side.
I got a piece of paper with the corners that said these corners are for show/offroad purpose only, they are not SAE or DOT approved.
The corners that I got came with amber bulbs that plugged right in.
I know for a fact the color of the reflector mattery, I'm not so sure about the color of the bulb.
I believe your reflector can be white(clear) or amber as well because some cars have factory white(clear) reflectors up front. As well as rear you can have clear tail as long as they have a reflector and light up red.
