taillights/blinkers/third light not working

[whiteram1500]

Hi so i noticed this yesterday a coworker of mine told me that one of my taillights were bad when i was leaving the job site. Which isn't usually a problem just replace the bulb. but that isnt the cause this morning i had a friend help me and none of my lights are working in the back! If anyone has had this problem please get back to me and if its a fuse which one would it be?

I had a similar problem. I added the factory rear centre running lights under the tailgate like the duallies have. I used a T connector to tap them into the license plate lights. One day I noticed that not only was the new light completely out, but so were both of the license plate lights. Now all lights mentioned are using LED bulbs but had been working just fine. The only way to get my license plate lights to work again was to disconnect the added lights. There was no short and no other rear lights were affected. No fuses were blown, I'm still scratching my head.
