LOL, what that light is telling you is that the overflow reservoir is low on antifreeze, if it is full when you look at it and the light is still on, the sensor may be bad.
yes a plant light is better. a normal incondescent lightbulb is practically useless for a plant.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
check ob1 codes by turning key on off on off on the mil light will blink out your code.
the brake light switch is on a bracket just above the brake pedal.
The brake lights and all of the rear lights can be access through the inside back molding in the rear. there are little knobs that you turn to access them.
Under the dash, look up above the brake pedal.
If you have the codes read and repair what is wrong with the vehicle the light will go out on its own, or can be reset by the tech.
