Ok, got it working thanks. I took both of the sockets out, it turns out the one that wasn't working had a metal clip not touching the metal on the bulb, bended back in place and it works.
Yup, the bulb is in all the way in the mount. And the mount/bulb is "clicked" into the light housing all the way, no light is coming in the back of it and I can't turn it any more.
I have an 08 Toyota 4Runner, Whenever I activate the right turn signal the dashboard turn indicator flashes about twice as fast as its supposed to and the back right turn signal doesn't work. I replaced all 4 turn signal bulbs but I'm only having problems with that one. I tested out the hazards...
