[DeW_H0e_GT]

also, i noticed the brake light went on when i was braking hard from a green light to red......i was crusing like 30 mph n then the lights turned red n i have to stop immediately...i see teh brake lights turned on......wtf????.....when i was braking i was noticing my handbrakes, but its securely off during driving.....and on another note, i was braking during a corner at 30 mph and made a sharp turn the brake lights turned on again....n went off within a couple of seconds.....any1 kno what could be causing this????
