Are Amber (Euro) Rear Turnsignals in USA Fixtures DOT Compliant?, Rear Euro Sidemarker in USA Fixture is Amber, not Red Options

[Spoke]

Just wondering if putting Euro rear lenses on USA fixtures with active sidemarker is USA DOT compliant. The Euro rear lenses have amber turnsignals which should be acceptable. However, the USA fixture has a sidemarker bulb which is red with the US rear lens and amber with the Euro lens.

This sentence was copied from a description of lighting:

"In the United States, the lens of a side marker, made of high impact, translucent plastic, is amber-colored for the front of the vehicle and red for the rear."

And this one:
Effective January 1, 1968, all passenger cars built for sale in the United States were required to display amber lights or reflectors on the sides of front fenders, and red lights or reflectors on the sides of rear quarter panels.

From Washington State Legislature:
RCW 46.37.100
Color of clearance lamps, side marker lamps, backup lamps, and reflectors.
(1) Front clearance lamps and those marker lamps and reflectors mounted on the front or on the side near the front of a vehicle shall display or reflect an amber color.
(2) Rear clearance lamps and those marker lamps and reflectors mounted on the rear or on the sides near the rear of a vehicle shall display or reflect a red color.

The LED boards that I make have amber sidemarker LEDs for amber rear turnsignals. It makes me wonder if the amber sidemarker LEDs should be shut off or constructed with RED LEDs.

Thoughts?

About 10 years ago, I got red rubber covers from my local flap to put over the rear side marker bulbs. The result was interesting. The whole amber lens corner was actually red when lights on but became flashing orange when the blinker was on. The power of the blinker bulb was far greater.

I did this after un-successfully looking for a red bulb for the side marker bulb size. After a few short years the red cover lost its color...

Fast forward to LED light era, I recently found red LED side marker bulb and put them on. The LED isn’t as strong as the incandescent so the result is not perfect but you get the idea...

If you are currently offering the updated side marker LED board, you might want to try assembling one with red LEDs and see the result. Obviously, keep the orange LEDs for the blinker.
