Toyota Repair: dash/light indicator on, phillips screws, camry v6

Question
I have 94 Camry, V6, 3.0L, and the dash indicator to check lights is on. I've checked all the bulbs on all the lights and they all work. Could there be a short somewhere?

Answer
Even though all the lights are working there could still be a problem with the bulbs, each bulb should be removed and inspected for any discoloration of the glass, if any bulb looks smoky inside the bulb glass it should be replaced, especially the third brake light, if all the bulbs are good then the ground connections on the bulb holders should be checked, they are the white/black wires held on by phillips screws, the bulb sockets need to be inspected for worn contacts, if none of those are the case then the lamp failure relay in the left side of the trunk may be the problem, it's located under the side carpeting mounted on a metal brace.
