i can only answer one problem which is the reason they blink so fast is becuz the car puts out a certain amount of current or voltage and if one of the bulbs are out (either front/rear) then the rest of the bulbs will get more volts which causes them to blink faster. this might be wrong but i know since i dont have a left turn signal bulb and it just blinks in the corner light (which hav a smaller bulb) and when both my blinkers were disconnected it blinked like hyperblinkrs.
