No walk away , i learned with you, thanks a lot, makes all senseMy kids eventually tire of me and walk away, so feel free to do the same.
Automotive lighting traditionally used DC power and/or incandescent lights.
Most cameras take images 24 times a second.
DC power does not cycle, or "flicker" at all, so all 24 times the light is "on"
Modern LED lighting is powered with AC power and is actually blinking very fast.
So fast your eye can't tell when it's off.
Your camera however, which uses modern optics but still films with one image every 24 (or 30 or rarely 60) times a second will catch some times the LED is cycled "off" hence the flickering.
You can fix this by matching the camera frequency with the light frequency (difficult) or just switching to DC power (easy)
Thanks for taking your time to make it very clear, got it.Switch your camera to manual or shutter priority and slow down your shutter speed until the flashing stops. This increases the length of exposure for each frame to catch multiple cycles of the pulse width modulation flashing of the LEDs. They are still using DC power, but since LEDs generally can't be dimmed efficiently, their brightness is managed by turning them on and off very very quickly, varying the amount of time theyre off versus on in a cycle will change their apparent brightness.
