Your definition is accurate outside North America, but not within North
America. In North America, DRLs are allowed to be white, selective yellow,
amber or any color in between. They're required to stay on with the
parker/marking lights by Canadian law. They're required to turn off with
the parker/marking lights by US law, but this provision is not enforced.
