Ok stupid question about LED headlights

I have a 2019 tundra limited crew max. Without pulling a bulb how do you tell if you have LED headlights?

 

You should have factory led headlights.

 

I don't even think that there's anything to remove on the LED housings. That's the case on my Sequoia headlamps...

 

Correct. It’s an integrated led on a board. Nothing to take out and see.

 

That make sense to me, but I didn't want to say "this is how it is" having never actually examined the Tundra LEDs.

 

By looking at how white and bright they are.

If they are dull and yellow, they are halogen.

There is a noticable difference between LED and Halogen.

 

Thank you.
