Tail light question

Dont have my truck at the moment and wont for a week or so and had a quick question. Getting ready to order all led lights and was wondering if since I have Blis are the rear tail lights already led or could they be halogen and have blis? Any way to tell without having the truck? I have the vehicle sticker if that helps.

Thanks

When you order with the led front headlights it also gives you led taillights. Halogen headlights gives you halogen taillights.

yes i have a 2019 250 sport and it has BLIS and halogen lights not LED
