My car has an automatic headlight thing, so when it gets dark the headlights come on automatically. The problem is that it doesn't work in the rain or twilight, and if I pull the knob to turn on the lights myself it just dings non-stop (it also dings every few minutes while driving, but if I hit the steering wheel it stops). If I pull the knob out it dings, hitting the steering wheel doesn't stop it. Here's the question: Where is the sensor that tells if it is dark out? Is there anyway I can put tape over the sensor or something so that it stays on all the time?
