my brake light sensor seems to be working fine that you sent to me a month or two ago. ever since i got it and installed it its still showing the rear brake lights error light on my dash like there is a bulb out or something. it only comes on when my headlights are on and i hit my brakes. a few times its come on without the headlights on. i've checked my taillights and brake lights and everything works but that little yellow/orange light comes on and is kind of annoying. any ideas as to what the problem is? is it a bad brake light sensor from factory?
