help! Need to know the name of this movie!
 

Hey guys! I've been searching for the name of a movie for a long time. When I was a kid back sometime around the early 90s I remember watching part of this horror film in a hotel... it involved a subway train and this red light thing that kept appearing and a guy(or girl?) running away from this light thing in a subway train. Then I remember there being a scene with a taxi driver (it may have just been a car?) and some blodied body being underneath the car. Sorry this is really vague but its all I can remember! If anyone knows what movie I'm talking about, please let me know! Been looking for this for ages! I think its probably an 80s/early 90s horror film. Thanks :)
