Did Light win even though he died?

No, but he did at least still live on as a god in the eyes of some people, as shown দ্বারা the girl and the others praying at the very end. His ultimate goal to create a world of only good people and be the LIVING god of it was not fulfilled, so he lost.

Pftt. No.
এল-মৃত্যু পত্র died too...and WON!

Hum...No cuz Near was the পরবর্তি এল-মৃত্যু পত্র and beated him...But he was sorta right just that he went crazy with that kind of power

Sadly, no~ *tears*

Yes, he won my heart. No matter what their goals were, fictional characters have success when they are unforgettable for some people, at least. And i wont forget Light.
