At one point or another, we all experience the phantom "bulb out" warning light.

I've solved it by taking my dremel with the small polishing head and polish the contact points in the sockets (especially the tail light sockets), as well as, the tip and the sides of the bulbs. Then I take a small screw driver and gently pry the sides of the contacts in slightly so that the bulb is squeezed snugly in the socket (doesn't wobble around in the socket). Lastly, I apply a little bulb grease to the tip and sides of the bulb to increase the odds of the bulb surfaces making good contact.
