Right directional is blinking faster than normal. All bulbs ae working

one of the bulbs has a burned out element,probably rear.lots of the bulbs have dual elements,and only one will go out.look close,and you'll see it.i think your bulbs are 3457 or 3757 amber,3157 will work also,but only little difference in wattage.if the turn signal is working,then it's the other element in the same bulb,parking or brake element is burned out.
