You're going to be disappointed. You'd need to blind yourself. That red wavelength is at the bottom of the visible spectrum. Any light that looks not-read is above this threshold. That includes old kerosene and acetylene lamps from before cars were common as well as all other "white", "yellow", or "amber" lamps.
Also, halogen is an old lamp type that has been in use since the 1960s. Then towards the 1990s, there were changes in optics with "projector" housings for halogens, and then the shift to high-intensity discharge (HID aka xenon) lamps. The latest ones now are LED, of course.
