I have a 2011 Ram 1500 Bighorn, I recently noticed i had to cab brake light or running light.. I checked fuse's and found i didnt have a fuse in that place. I fixed that and upgraded to an LED all in one cargo light/ brake light and running light, After doing all this I found I still have the cargo light and no have the running light but no brake light from the cab. All other lights work. Is this an issue with a brake light switch under the pedal or something else?

 

LED's require load resisters. Here's a post with the same issue.

I was told these were just plug and go. Why would the other lights work within the light housing just not the brake light?

 

Are you getting a light out indication in the instrument cluster or is the only indication of a problem the visible lack of a brake light? If you're not getting a lamp out notice the lack of a load resistor may not be the problem, but may instead be an issue with your LED assembly or wiring to it. After all, if the fuse was missing, it's probably due to some other problem that a previous owner apparently wasn't able to easily fix. Do you know if the brake light was working before upgrading to the LED assembly?

I am not sure, I bought from a used dealership, and it apparently wasn’t checked. I replaced that fuse, went back to the original light as well with new bulbs. I still have running light and cargo light but not brake light. I also didn’t have license plate lights, changed the sockets as they looked a little burnt and still don’t have those either. Also I just noticed when I turn my running lights on, the rear don’t turn on but brake lights and turn signals work on rear

 

Not messages on the console about anything..is there a fuse for the plate lights or something? Even the rear running lights? No manual with the truck
