The reason you see Hondas with wobbly lights is that in the olden days headlamp assemblies were mounted on bodies with plastic, which degrades, snaps, bends, etc. A lot of older cars do that.

The reason they flash is that the ballast is just giving the bulb the initial high-voltage zap (the arc). As you aren't really feeding that much current through the bulb that way, you aren't appreciably shortening its lifespan.
Yeah, this is what I thought. Isn't that what we were saying??

Flash-to-pass, as vehicular equipment, has been standard since at least the 1940s, in various forms.

I'm very saddened that some drivers don't seem to be knowledgable on this topic.
This ^^^ It's common knowledge where i come from too.
