FD3S headunit and headlights fuse problem! Help needed!!

[VishalStar]

Hi guys,
 
Hoping someone can help. The other day i was experiencing some battery problems with the negative disconnecting. All fixed now but i believe the power on/off shenanigans have caused some fuses to blow. My headlights are no longer popping up (although the lights are still coming on) and also my headunit refuses to turn on. The reading light still works.
 
Dont know if any of that makes sense but some help would be really appreciated. Driving at night is scary with just the sidelights! And the lack of music nearly bored me to death on my drive to bristol!!!
 
Cheers
