Related, but are most people unbothered by LED tail lights / brake lights? The flicker drives me nuts.

If they flicker it's because the designers/engineers did something wrong. It's an entirely DC system, so the only way they would flicker it's if they're using PWM control for the intensity of the lights. There are better ways to dim LEDs, which don't introduce flicker.

Every single vehicle with LEDs does it.

Yep, because they're cheap. I don't notice it anymore, which only tells me that things have improved, I used to see it a lot with brake lights. Not so much with headlights.

I dunno why they're horrible, I just know that's an effect of PWM control that's been set up pretty poorly.

I'm not an engineer, nor do I work on cars, either designing them or fixing them. I'm just some guy.

That, and the fact that a lot of them are too small.

[–] merc@sh.itjust.works 1 points 3 months ago (1 children)

Too small to see? Or too bright because they're really small? Or what?

[–] umulu@lemmy.world 1 points 3 months ago (1 children)

Too small to see. You can be paying attention to the road, and those small led blinkers will go unnoticed most of the time.

I've never had that problem. They're normally clustered into a cluster of other LEDs.
