My brake pad warning light came on so I bought new brake pads and changed them. My brake pad warning light is still on!..it turns on when I start the car and stays on until I turn off the car. How do I turn that light off? Changed the brake pads the next day after the light came on.

You forgot to replace the brake light sensors. They are about 15 bucks, and have to be replaced in order for that light to turn off.
You can either get them from the dealer where they'll likely charge you 3 times as much, or you can go to http://www.turnermotorsport.com and get them there.

You have to reset the light by leaving the ignition switch on position #2 for about 30 sec. turn off the ignition and start the engine up and see if it goes out.
I recommend buying a new wear pad sensor as well because now light will lit up when you're way below spec (less than 3mm)

Obviously the wear sensor has made contact with the rotor and is already damaged. You're not even suppose to resuse the wear pad sensor if its worn or damaged anyways.The way how the sensor works is that it must make contact to the rotor to complete the wear pad light indicator circuit.
There is no mentioning that he replaced the the wear pad sensor with a new one.
But if one did replaced the wear pad sensor and the wear pad indicator is lit up, the way to reset it is to leave the key on in ignition switch #2 or #1 for about 30sec. turn it off and its reset.

Actually the wear circuit is already made with the new sensor. When the pad wears down and the sensor starts to rub on the disc, it will eventually wear into the sensor and break the circuit. Try measuring one with an ohm meter. Both new and used.
It is possible to bypass the whole thing (but not recommended unless you are very anal about maintenance on your car) by cutting the cable on the sensor and then connecting the two wires together. Then sealing them with RTV. You will never have to worry about that light again but you will have to pay attention the pad wear yourself.
