easiest way is to check all the fuses in the box under the hood.. make sure they're good
also check the drivers side kickpanel for any blow fuses... there is a brake light relay and 15a fuse in there
i would say it's just fuses
if all fuses check out ok check the silly little yellow (i think it's that colour on your side of the world) box underneath the taillights as water has a habit of leaking in past your lights onto the box and nakering it out over time
good luck with it
