    Seriously... Check belt tension... If belt starts slipping and alt. isnt charging right it WILL cause those lights to come on. Had serp. belt on H6 motors and alt. belts on wrx's break and had the same prob. Also it could poss. be an alt. prob. DO NOT GO TO ADVANCE OR AUTO ZONE to have alt checked. Take it too a reputable shop that spec. in Jap. cars and ask them to test alt. check belts etc. and if alt. is undercharging to do a full check of all connectors on alt. and wiring...While its there have them scan the ABS system for trouble codes. It will give you a good idea of whats going on...AND it sound kinda like a belt in the way that it does it under heavy accel. when its raining...Think about it...

    Master cylinder shouldn't but the brake lights coming on probably will. The lights take more power than most people think. Incandescent lamps are the most ineffiecient type of lights available, but they're cheap, so they're popular.
