Headlights - Black Crystal question

But crystal is highly reflective

Click to expand...

There is no crystal present in these "headlamps". The "reflectors" are black plastic, and the lenses are poor-quality glass. That word "crystal" is used for marketing promotion, not to refer to anything real.

Hit the brakes, dude. Throw it in reverse and nail the gas; you're on the wrong road. Those are not headlamps, they are gumball-machine-grade trinkets from China. Not capable of providing even minimally adequate amounts of light for a quick run to the store in a well-lit suburb, let alone enough light to keep you out of a crash on a dark road.

That description applies to everything (each and every single item) offered by "Octane Lighting" and "Dapper Lighting" and numerous other vendors. Keep this crap off your car if you ever drive it after dark. And that's without even getting into the hideous danger caused by other-than-white-or-yellow light facing front. Red light from your front lights is a severely bad crash begging to happen.

Disregarding the mountain of garbage on the market, there are a lot of good options across a pretty wide price range, and soon there will be more/better. Stick to actual, real headlamps made by legitimate companies. Some suggestions are here and here.
