Can the shop replace what I think is an LED headlight, that is burned out?

Yes

They should be able to fix it.

Thank you for the responses. I should have been clearer. The vehicle is a 2015 Freightliner Cascadia. I am familiar with the regular headlight bulbs but have never encountered LED headlights before. I will be going to a TA tomorrow.

Yes they could or call local auto parts place.

Yea if they have it in
