I have two Magicshine knockoff lights that have failed in the same manner. they no longer function on any of the THREE factory settings - low, high or strobelike flashing. However they both will flash at about 1 flash per second. Unfortunately that's to slow to be of much use.
Is there any way to get these lights back to a steady-on light?
Here's an image of one of the lights i put an amber lens on to use as a blinking tail light in the countryside at night.
