Auto Stop Start Headlights Dimm

I owned a Prius with auto start and never once saw the lights dimm with that feature on. Currently driving a loaner 2020 Ford Explorer and lights do not dimm with the auto stop start feature.

I have a 2019 Ford Expedition from day one I noticed headlights dimming with the auto stop start.

Is this normal?
Anyone else having this issue?
Anyone headlights not dimming with the auto stop start?

My platinum 2019 with led headlights do not dim. Might want to have your battery checked.

Mine dim too. Even wife noticed and asked if this is normal!

I thought it is normal given the load on battery during start

Totally normal!

I don’t think this is normal I think Ford forgot to add a battery capacitor kind of like what they do when you add a big sound system in a car when they bass hits the lights won’t dim

My expedition does it, my F150 did it, my Audi does it. lol

If you are concerned I would advice visiting your service department. Let us know how it goes

Auto stop start strikes yet again! Disable that nonsense.

Anything that puts extra load on the electrical system will cause incandescent lights to dim because there is a slight voltage drop. STarting absolutely will cause a momentary drop. This may not be noticeable with LED lights due to how they are made. The power windows on my jeep cause a slight dim of the head lights. It may happen on the expedition too but haven't checked. It is totally normal and nothing to worry about.

I know little to nothing about the 2020 loaner Explorer OP was driving. Went to Ford website today to 'build' one and was kind of surprised to see LED headlights as standard equipment on the base model XLT.



And of course, Ford contradicts itself regarding the highbeams:

Standard Features
Exterior Features

• Headlamps – Autolamp On/Off, LED Low and High Beams with Courtesy Delay
• XLT body color door handles
  
• Body-color liftgate spoiler
  
• Black mesh insert with chrome bars
  
• Headlamps – Autolamp Auto On/Off, LED Low Beams, Halogen Reflector High Beams

And if you continue reading, you'll learn that Easy Fuel® capless fuel filler is (somehow?) an interior feature.
