Hello!

So I noticed my bed lights no longer come on. Yesterday i replaced the upper cargo lights with LED and thise work great.

are the Bed lights and the cargo lights on the same circuit?

not sure why they are not working now

 

You don't mention year of truck (create a signature, it really helps), but on my 2017 the cargo light and bed lights are separate switches.

 

Mine stopped working also, before that they would come on and off randomly. Dealer replaced the button in the bed and seems fine now.
