When I turn on my headlamps on they tend to go on & off? What would cause this?

Thank you for the message there I sure appreciate it. I find that when I push the switch inward with a little pressure on it, they have lights come on and they stay on as long as I have the pressure on it if not they turn off momentarily. I'm curious how to deal with this? Is there a screw to tighten right behind the orange indicator lands on the switch that pull that off how does that work? Thank you very much in advance. Bob.

The knob for the light switch just pulls of , then there is a big nut that holds the switch in , its not very tight can use a pair of pliers to undo . good luck

Thank you I'll give it a shot , just tighten it right?

you will probably need to change the switch
