It works for lights and blinking, but once I turn the blinker stays on and continues to blink. Very annoying! I have tried loosening the screws to make sure it is not binding, tried pushing it in and tightening it, even oiled it, but it fails to turn off. You can manually turn it off but half the time I forget and go blinking down the road. Find a different blink switch. I’ll have to find another one.
