Trailer Lights Question - Rear Side Lights

[dieselscout80]

What is the correct color for the rear most side trailer lights is it red or amber? I know the other side lights are amber.

I'd look are my trailer, but I noticed that all the side marker lights are BADLY faded.

Mine all have red.

Red, most tailights have a red window on the right or left side so they're rear marker lights as well as rear side lights as well

Thanks

My googling failed all I found was a picture that showed red, but didn't say if it was a reflector or light.
