I don't think that the vampire at the end was Evil Ed (even though they put in the voice-over teasing that it might), as in Fright Night 2, Charlie's psychiatrist specifically states that Evil Ed was killed by Peter Vincent.

Even with that, according to the rules the Dandridge had to be killed within 12 hours of his victim being turned in order to turn them back, and Evil Ed had been bitten long before Amy was.

I believe the rule stated was before dawn. Nothing about a specific amount of hours. Even if we assume the rule is 12 hours then Ed's turning would fit in that time frame as well since it was most likely past 7:00PM since they were to meet Vincent outside of Dandridge by 6PM and he was late. I speculate that Tom Holland, the original writer/director of the film did indeed mean that to be Ed at the end and just sloppily forgot about the rule he imposed. I guess it could be argued that since Ed wanted to be a vampire, he therefore remained one.

If the rule to save Amy was to kill Dandridge by midnight then why was Evil Ed still a vampire at the end?

My read on this situation: filmmakers are in the business of entertainment, not delivering everything with mathematical precision. They likely didn't notice the inconsistency that you've detected here, Naz, much in the same way that relatively few folk have ever recognized that James Bond isn't much of a spy or even an assassin, so much as he is an all purpose action man

Yes, especially in the 80s where as long as the action moved along you had a fine film. No time to think about incidentals like logic or following what was previously stated to be the rule. 😜

Still a fine film though. Has a really good score.
