Toyota Repair: 1998 Toyota Camry, bulb replacement indicator., toyota camry, dashboard light

Question
Dashboard Light replacement indicator comes on, and remains on, with all lights working normally. None of them appear to be brighter or dimmer than normal, but wonder if there may be some problem beyond the lights themselves. Have any thoughts on this ? Car has 45000 miles and problem has surfaced within the past couple of weeks. Is there some part that needs to be replaced.
Thanks for your time.....

Answer
Even though all lights are working I recommend that you replace "all" the bulbs on the rear, I just recently had a camry at the dealer that did the same thing and replacing all the bulbs fixed it, try this and if you still have the problem let me know, there are a couple of other things that could cause it.
