I have a single bulb on the right side that won't light when I press the brake pedal. I've been looking around on here and still haven't found the answer. Here's what happened:

I was sitting at a Taco Bell drive through when my lamp out indicator lit up. Next day I go out to look at it and found the right side inboard brake light was out. I replaced the bulb, didn't work. I started troubleshooting and discovered the light failed to light when the brake was depressed. Also when the drive lights and headlights are on, the running light turns off, leaving the light completely dark. The running light works, just the brake light cuts out.

I'd appreciate any help you could give me.
