LED 3rd brake light not working

[Sam Zachow]

I recently purchased a new cab brake/cargo light that is LED. They stated it was plug and go. After installing it, I found i still had the cargo light but no brake light or running light. That problem i thought was a fuse issue so i replaced the fuse and gained running light. I still have no brake light working. all other lights on the truck work and i dont get any error message anywhere. Is this a brake lamp switch like ive seen or something else? Got from a company called Cell-led in washington.

The 3rd brake light isn't supposed to have a running/park light. It's only a brake light with the cargo lamp.

I would check where you got it from about that.

Brake light and cargo light only. If your brake light worked before on the old one, then seams logical something is wrong whit the new one, if you not getting a brake light
