I saw this on TV in either the late 80's or early 90's. There are unfortunately only a few scenes that stick with me.
In one a vampire is in a room when suddenly UV lights come on, implying that they were harmful to him (I seem to recall another person in the room wearing sunglasses who wasn't as distressed).
In another scene near the end a blonde woman 'stakes' the vampire villain from behind (not sure if the woman was also a vampire, but I suspect she was).
In a third scene just before the end credits the vampire villain is being moved in a box, his body propped upright- when as a result of being jostled the stake falls out of his body, suggesting he would come back to life.
The movie was in colour, any dialogue was in English, fairly certain it was made at least early =-mid 1980's.
