From evening drives to navigating a house or a park in the dark, there are so many situations where it'd be handy to slip on a simple pair of night-vision lenses and the world that's beyond human optical perception could be illuminated like never before. This vision could be a reality, with a…
Well, IR isn’t heat, but it’s associated with it. And since laser and LED lights heat up a little bit, yes, they of course produce a miniscule amount of IR. But it’s pretty much negligible in comparison to their visible spectrum emissions. If you’re already being blinded by the visible range of the laser, the IR part isn’t gonna do much.
Fair enough, I was being too vague with my statement. I was implying that they don’t emit much IR, as all bodies above 0 Kelvin do emit it. And LED/laser headlights almost don’t, in comparison to xenon and stuff. I looked up some Xe emission graphs and some even straight up show the peak in near-IR, while laser/LED starts flatting out way before NIR.
IR is heat, so headlights produce a a lot of IR. Laser headlights emit less IR with the visible light, but radiate heat.

You asked if headlights emit IR because you didn’t think they do, they emit IR.
