Converting Clear Fog Lights to Amber - 420SEL

[Cigar Havana]

I am about buy a pair DEPO euro head lights for my 420SEL. I notice the fog lamps are clear. Is there any way to convert them to amber, like the original fog lamps? Can open them up and put an amber reflector. Do the sell amber bulbs?

Thanks,
Joe

PIAA makes some crystal ion or something like that which work well.
