Two-color side marking with the option to choose your own color. Both colors can be chosen separately. The marking is made in such a way that when you connect the amber color it replaces the white color. Amber is then dominant over white. You can use this if you want the lamp to switch between 2 colours.

This lamp has a dark lens, also known as a dark or smoke look. It is multi-voltage and has E-mark on both colours. So versatile.
