A TRACTOR TRAILER WAS PASSING ME ON THE INTERSTATE. JUST AS HIS TRAILER WAS APPROXIMATELY 2/3 PAST ME, MY LIGHTS DIMMED OUT ON MY CAR BY THEMSELVES. THE DRIVER OF THE TRACTOR TRAILER THOUGHT I HAD FLASHED MY HEADLIGHTS AT HIM, TO LET HIM KNOW HE HAD CLEARED MY CAR AND WAS SAFE TO COME INTO MY LANE, WHICH WAS NOT THE CASE. THIS MADE THE DRIVERS BEHIND ME AND THE TRACTOR TRAILER IN ALL 3 LANES, TO SLAM ON THEIR BRAKES. THE TRUCK DRIVER ALMOST LOST CONTROL OF HIS RIG TRYING TO KEEP FROM HITTING ME WHEN HE REALIZED THAT HE DID NOT HAVE CLEARANCE AS MY LIGHTS "SUGGESTED" TO HIM THAT HE HAD. ALL OF US WERE FORTUNATE AT THIS TIME NOT TO HAVE WRECKED. (YET I RECEIVED A LOT OF JERKING OF MY NECK AND HEAD WHEN BRAKING AND STEERING TO GET OUT OF THE WAY). NEXT TIME MY LIGHTS DO THIS IT COULD MAKE ANOTHER TRUCKER OR PERSON PULLING AN RV OR A SCHOOL BUS FULL OF KIDS OR TOUR BUS FULL OF TOURISTS THINK I HAVE GIVEN THE "CLEARANCE" TO MOVE INTO MY LANE; WHEN I HAVE NOT. SOMEONE IS GOING TO GET KILLED IF THIS ISSUE WON?T FORCE TO BE REPAIRED BY GM/SATURN. I REPORTED TO SATURN, WHAT CAUSED THIS SEVERE POWER DRAIN ON MY CAR. WHEN THE AUXILIARY COOLING FAN NEAR THE COMPRESSOR KICKS IN, IT PUTS A SEVERE POWER DRAIN ON THE CARS LIGHTS, WHICH WAS USING THE HEAT OR A/C THAT COULD BE DOZENS OF TIMES IN A MATTER OF MINUTES IF IT APPEARS THAT I AM FLASHING MY HEADLIGHTS TO THOSE IN FRONT OF ME AND TAPPING MY BRAKES TO THOSE BEHIND ME. LAST WEEK, MY LOCAL DEALERSHIP WAS TRYING TO FIX MY CAR
