Great. You can use them to blind everyone behind you.
They are backup lights - they only come on when vehicle is in reverse, running, and the parking brake is off. Unless someone is immediately behind a parking space I’m trying to parallel park in to, at night, nobody’s going to be blinded.* And, maybe not even then. The beam spread / dispersion is almost hemispherical, emitted from an apparent source (diffusor / “lense”) of 10+ square inches. It’s probably no more glary than an exposed soft white 60 watt ceiling light bulb, IF the actual output is 800 lumens (unlikely). Breaking the originating source into 6, instead of a near point source filament, may help too.
*In the case given, they’ll probably be happy I can actually see them.
Not that excessive glare is not a valid night driving concern. But, that’s mostly headlights mis-adjusted, those dang bluish bulbs, or LED bulbs not certified for headlights (where you need a near point source for the headlight optics to properly chop off the top of your low beams’ pattern.
