Marker light mystery???

[a12play12]

Hi everyone,

83', 380SEC, I read somewhere that there are 3 different color front marker lights available for my 126, white, and 2 shades of amber. Right now i have 1 that is very dark amber and 1 that is light amber, almost yellow,(does not appear to be faded), i would like to get 2 matching, and like the looks of the dark amber light. does anyone know what the difference is and how i could order the darker lens?? (IE. euro, american???).
Thanks in advance,
Roger
