"One: modern lights are HID, not LED. Totally different technology."
Try again. Many newer cars are LED by OEM. I design LED lighting, so I'd be in the perfect position to know this.
We're not talking about the accent lighting. We're talking about primary lighting, where LED is very, very rare as it's only the last 24 months or so that LED clusters with high enough output have started to come to market. Incidentally, I am your boss, so I'm in a super-perfect position to know this.
"Two: what are you driving? I've got a... car. With the cut-offs in my HID projectors, 100% of my light emission is at or below the bumper level of a car in front of me."
Totally against DOT regulations, you're using illegal headlamps, idiot.
Personal? You want to get personal? I wouldn't do that. Because that'd be the bit where I drop the simple fact that I'm running a 100% OEM factory install from one of the Big Three. My totally-against DOT regulations lights? Standard for a vehicle chassis that is pumped out in quantities of 100k a year. Of course, the HID option has only been available for the last seven model years, but the point remains. Your alleged expertise in the matter has just been made questionable to the point of oblivion.
"What, what? Making stuff up are we? HIDs are available at a very, very wide color temperature range. Mine for instance are a nice 4300K; a nice crisp white light."
4300K has more blue than STANDARD 3,000K. Try again.
By definition yes, 4300K has more blue than 3000K, which is very yellow. In any practical measurement, it isn't until you exceed 5000K that blue creeps into the visible spectrum. Headlights between 4300K and 4500K are considered white. 3000K isn't normal for this application. But given you're a lighting engineer for God or something, I'm guessing that you can't handle every color temperature chart and sample on the planet disagreeing with you.
"Again, your mirrors are evidently below typical bumper level. Weird. You might want to fix that."
Ignorant of how physics, light, and mirrors work, I see.
Yeah, I've always had trouble with the idea that things above lines where light is not permitted to travel somehow reflect blinding light at someone. It's a failing, to be sure. Dude, we're not talking about passive reflected scatter photons bouncing off pavement. We're talking about shooting people in the face with headlights. Do yourself a favor and Google a few dozen images of "HID cut off" and take a gander at how the only area where anything is thrown more than about 2ft above the ground is the extreme right edge, if even there. It may save your job.
"It's not an issue with OEM installs."
Which is why Ford and Toyota are asking me (and several other companies) about LED designs and fixtures and remedies for the problems they're having.
Please shut your mouth. I design this equipment.
If you do have a job in automotive lighting, you shouldn't.
