I understand that the USCG will certify a light based on it's brightness, arc of visibility, and color spectrum, but NOWHERE in the COLREGS can I find a reference to color spectrum beyond the words "white, yellow, red, green" etc.
The standards by which nav lights are built is published in the CFR (Code of Federal Regulations). You, as a used boat owner, are NOT required to have "certified" nav lights or install them UNLESS you are a boat builder or re-seller/broker/dealer. If you buy a new boat in the US it WILL have certified nav lights or the builder broke federal regulations.
If you are a builder you must use USCG/ABYC A-16 nav lights properly installed and placed for proper visibility. All USCG certified or ABYC A-16 lights will meet the minimum standards as set forth by the CFR. This is what labs like IMANNA use when testing nav lights to USCG/CFR nav light standards..
