Confused LED Tail lights 2018 Silverado LT Z71

[al210]

I was thinking about upgrading my tail lights to LED on my 2018 Silverado LT Z71.

 

I was under the impression that the stock tail lights are not LED? 

I was looking at the Spyder 5079992 https://www.spyderauto.com/product.php?id=ALT-YD-CS14-LBLED-BSM

 

Their web site says they fit. On other websites that sell them they say they don't fit my vehicle.

These are the ones that convert the signal to LED.

I thought the 2018 silverados did not have LED tail lights unless it was the High Country?

16+ Silverado LTZ and High Country have led tail lights.  LT has halogen tail lights

LT models with the 'High Desert' package also have LED taillights.

My tail lights have the three bulbs so they are the halogens I guess.
