My brake light started coming on when I'm accelerating and brake kinda hard. What da dilio? Never done this before.

 

Low brake fluid level.

 

Need new Pads? Same thing happened to me and I just needed new pads.

 

same thing started happening to me recently.. my brake fluid is ok, i'll have to check the pads i guess... but even though there's no squeaking when i brake?my car's an 05 bought in jan 05

sometimes the brake light will come on when i'm not braking, then turn off after about 5 minutes or so

 

See the thread about ABS, TCS, and SLIP light.
