so last night leaving work, i thought i had a headlight out, so i went back inside and bought a 2 pack. headlight was not out, it was just really dim. i would say maybe at 10% brightness. so i swapped bulbs and no change. car is a 95 dx coupe, and i converted it to right side drive. im using my left side drive harness, i just flipped it upside down so everything would still plug in. ive tinkered with the wiring but dont really know what to look for. i tried messing with the ground junction box that mounts on the inside kick panel with no change.
also i have my prop valve on the inside firewall, and the extra hole, i dont know what its for, but its leaking when i press down the brake pedal. its on the side where the lins go in from the master, and out to the front wheels

oh and ive been driving the car for 3 months with no problems so this isnt a "i wired somthing up wrong or did my brakelines wrong" kinda thing.
