I believe the regulations are still in force. But I have a hunch that the regulations have not kept up with progress in the technology of light sources, and may be based on the assumption that the source is an incandescent filament.

That stopped being true in the late 90's/early 2000's when HID headlights entered the market, and the standard was further updated a few years ago (after a decade's delay) to allow for adaptive-shape headlights (ie ones that can control the shape of the high beam, for example to still provide high beams, but not in areas occupied by oncoming traffic.)
