I have a 1991 Firebird Formula. Last week, I noticed that my taillights had 2 bulbs burnt out, both on the right side. I also saw that my center stop light (in the hatch) had also burnt out. I figured I would replace all of them while I was at it. So, I replaced them all, and the regular taillights were fine, but thwe hatch light still wasn't working. Then, last night, I noticed that the 2 right-most bulbs in the right taillight had burnt out again. I replaced them, and now, not only do they still not light up (neither with the parking lights on, or when I press the brake), but I now only have obe working brake light (the inner one on the left taillight). Does anyone know what I can do, before I get a ticket, or someone slams into my rear because my lights aren't working?

These types of problems are almost always caused by bad ground/s or corroded wires/connectors. Pull the bulbs and check the sockets, then check the ground wire/s and the wire harness connectors. Coat any possible water entry points with dialetic grease or electric sealent paint.
