Do this test. Turn on your headlights, go to the back of the car, see if your right tail light is out. Then go to the front of the car, see if your front running light in the headlight (orange light) is out. If it is then you likely have a compromised wire somewhere in the car. Check all related fuses and relays inside the car and in the engine compartment first, as those are the easiest, and then proceed to check the wiring. I posted to a thread here named "Cluster Out" with more detailed information if you want to check what I said in that post.
