OK, I UPGRADED MY SOLAR NIGHT LIGHT. AT FIRST IT SEEM LIKE IT WAS WORKING GOOD BUT THE LIGHT WOULD DIE OUT A FEW HOURS AFTER THE SUN HAD GONE DOWN. I THINK ITS BECAUSE THE SOLAR SIDEWALK LIGHTS GET DIRECT SUN LIGHT MOST OF THE DAY. THIS WAS HANGING IN MY WINDOW GETTING LIGHT BE NOT ENOUGH TO GIVE THE BATTERY A GOOD CHARGE. SO I WAS AT THE DOLLAR TREE AGAIN THE OTHER DAY LOOKING FOR SOMETHING TO HANG IN THE WINDOW SO I COULD HIDE THE SOLAR CELL BEHIND AND BIG ENOUGH TO ADD ONE MORE CELL. AS YOU CAN SEE BY THE VIDEO I FOUND THIS PRINCESS
WINDOW HANGER THE YOU HAVE TO PAINT.
AFTER PAINTING IT I GLUED THE ORIGINAL SOLAR SELL BEHIND IT AND ADDED ONE MORE CELL TO IT. IN THE NIGHT LIGHT BASE I TOOK IT BACK APART AND ADDED TWO JUMPER WIRES TO ANOTHER BATTERY TERMINAL AND ADDED 1 MORE BATTERY.
FOR THE PAST TWO NIGHTS IT HAS BEEN RUNNING LIKE THIS. THE LIGHT STAYS ON TILL I GO TO BED. I DON’T KNOW HOW LONG IT SAYS ON FOR BUT LAST NIGHT I WENT TO BED AT 12am AND THE LIGHT WAS STILL ON AND BRIGHT.
