Oxford White & Atlas Blue F-150 Lightning XLT Spotted

It's a byproduct of LED's, which is safe to assume they are using there...

Here is a technical breakdown:

To the naked eye it will appear solid.

That explanation works for A/C powered LEDs, but not really for D/C powered ones like on vehicles. I haven't seen a good discussion of that.

You are right that LEDs do not necessarily flicker when powered by DC but many LEDs adjust their brightness by using pulse width modulation. PWD rapidly switches on and off the LEDs to get the desired brightness. Not 100% sure that's what's going on here though. You really see the flicker on some of the videos that have been posted here.

Good catch! Thank you.

I do still think that to the naked eye you won't notice an issue.

Completely agree - this is an artifact of the digital camera filming somehow - I am just curious of the physics.

All LEDs on vehicles will use Pulse Width Modulation (turns them on and off faster than the human eye can see) to adjust the brightness of the LED. This creates a frequency that will interact with the shutter speed of a camera hence the appearance of flashing. Even at full brightness, sometimes manufactures will overdrive the LED to get it brighter than just giving it straight DC power. With the PWM the LED will survive this overdrive, but without it would kill the LED in a matter of seconds.

Yes DRL LEDs on vehicles do dim - they are full brightness during the day and dimmed down at night.

Thanks - that makes sense.

Judging by the wheels and black door handles, the Blue is a PRO model…right?

I believe they are both XLTs. The white is the XLT Plus and the blue is the regular XLT.

No - it has the front light bar, which would make it an XLT with the 18" wheels. That said, these are prototypes so some of the details and trim could be non-standard (i.e. wrong).
