I know this sounds like a dumb question but does anyone know if a headlamp would have a thermal overload built in? I can't imagine it would. I am using a GP Thunder Plasma-White H11, 8500K/55W Quartz Glass Bulb for my low beam and it is cycling on and off. There doesn't seem to be a pattern to it. Most of the time it is on but it will occasionally go off for a minute or two. I know that it is most likely a loose connection somewhere but as of yet, I haven't found it. Maybe they are just cheap bulbs and not very reliable. The odd thing is a fairly new lamp blew out and the second one is cycling on and off. Anyone else have any experience with these GP Thunder's? I like the color they produce but they really need to work.
