Flicker should be well above perception level, as demonstrated by
numerous crap car tailight designs this basic appears to have escaped
some makers.

Some car LEDs are driven in a very different way from domestic mains LEDs.
Basically, you can't just transfer a problem with those to all.

It is an example of how even well funded, well informed designers can get it wrong.

Guess that someone read something about getting more brightness out by pulsing and missed the rest of the article about average power.

Result being the strobe tail lights fitted to some early LED equipped cars, not got cheep Chinese knock offs to blame either ;-)
