I have never seen led rings not white. The only way you will achieve that look is with "gels" as in what stage performers use to tint a spotlight.

If you can get inside you could use Amber tape like kapton tape or possibly Amber window tint over the whole lens. Since white is not a good color for actually seeing it will improve the visibility at night if the color temp of the main headlights are also lowered to 4000 ish.
