What better light! — Toyota Sprinter Trueno, 1.6 liter, 1995

The theme of light (lighting the roadway), I think, is relevant and topical for everyone ...
What needs to be done so that the roadway can be clearly seen at night?
When I bought the Toyota Sprinter Trueno, its headlights were frightened by life (darkened plastic, slightly clouded reflector). The first thing that was done was the replacement of standard lamps (what to choose, standard, halogen, xenon?). The standard was already standing - not an option, xenon with embossed glass - not an option, halogen - the remaining and only right solution. The disadvantage of halogen lamps is that the more powerful (brighter) the lamp, the shorter its service life, so it is better to take a high-quality one (Koito, OSRAM, Philips). I took Philips (about 1000 rubles for a pair of H4). Lighting is a little better, but not much.
It so happened that I got into a mild accident, from which the headlights just flew out, and of course they needed to be replaced. I wanted to take restyled ones after 1997 - crystal, but they were not available and I had to take the same ones (with embossed glass).
What was my surprise when I turned on the headlights at night: a bright, even light illuminated the road.

I would like to summarize this scribble:
The quality of road lighting directly depends on the totality of all lighting elements.
In order for everything to be good, we need: clean transparent headlight glasses (which fade over time), a clean, well-polished reflector (mirror), a high-quality lamp with a burning (glow) temperature close to sunlight (white-yellow).
Not any blue, lilac, etc.
Maybe they paid attention to street lighting ... Which is better, white or orange lamps?
