Problems after Battery Replacement (Blinkers/Radio/Dash: Lights)

[GrapeApe123]

I've recently changed my battery after my last one kept dying on me. Now, car runs fine;

But ever since I changed to the new battery my Blinkers aren't working at all (hazards do work though) and my radio and dashboard are extremely dim to the point where it looks like their completely off.

Does anyone know why this is? How can I fix this?
