skylines are techo
it only beeps in the cabin, not outside, so its not a bulb,
it will beep when u leave the keys in and the lights on,
u cant pull the keys out if u dont have it in park (auto)
and u cant put it into gear out of park unless u toutch the brakes(auto)
u feel the seat belt move a lil when u do certain things so there are tensioners,
