Hey everyone! New owner here. I was watching some reviews before buying the car and I noticed that some reviews had a cool effect to the heartbeat DRLs. I can’t seem to recreate it though. I tried turning the fogs off, turn signals, and hazards but no luck. Am I missing something?
The effect I’m talking about is 3:10 into the video. Example

You can’t. I believe that’s just the nature of how the camera picks up the led light unfortunately. Would be really cool if you could though!

I dunno. It looks too perfect for it to be that IMO. I feel like it would be blinking if it was a weird camera issue. Bummer though

its the frame rate of the camera being faster than the rate of the pulse width modulator for the leds. basically the leds are constantly in a flash but at i high frequency'

Yep, this is exactly it. If the lights were shot with 60 FPS and 120 FPS, you'd see a difference between the two in terms of the "pulsing" speed.

I really wished they actually had the heart beat design, it looks so sick. The first time I saw a K5 on the streets I swore it had a heartbeat flash. Made me fall in love right then. I wonder if an arduino can replicate the heartbeat pattern or some custom shop can do it.

It's the same strobing effect that you see in marketing videos of a car alone on on a scenic highway where the wheels seem to be rotating backwards. The marketing department likes that effect because it catches your attention. 🙂

As for the DRLs, if it were possible to have a dial that linearly controls camera frame rate, you could even control the perceived direction and speed of the heartbeat.
