Dangerous Turn Signs, USA Versions

[JoePCool14]

Hello, I'd like to make a request for the Dangerous Turn Right/Left signs that are currently white on red/red on white to be slightly modified to create a new version that resembles American road signs. In this case, they would be a black chevron on a non-neon, standard yellow background.

If these could be implemented, that would be excellent and very much appreciated!
