The engine warning light for emissions might come on in a Toyota Celica if the Oxygen Sensors are bad. It might also come on if the catalytic converter is not working properly or is plugged.
Could you please narrow down what lightbulb?
The fender must be removed so the light will slip out

If you press the brake down and the light comes on, a brake light is out. If it is on with your lights on, it means a tail light is out. The warning references are on page 47 (89 celica) manual...
It's most likely your alternator going out, or something wrong with the charging system.....
It is most likely your oil pressure light if it is red
The voltage regulator inside the alternator will malfunction. Often, all the warning lights will come on: brake/batt/etc. Replace alternator.
You have to pop the panels off inside of your hatch, right on the other side of the tail lights, you should be able to see the back of the tail light from there.
