I have just trial fitted some led headlights and was suprized at how effective they are, however since fitting, the Pektron unit which has hitherto been virtually silent in operation now emits a loud buzz when the flash facility is operated. Is this an indication of damage or potential damage? Anyone know why LED's should cause this? I am assuming it is the Pektron unit as it seems to come from that vicinity.

Mine does that as well when I operate the flash, but I have ordinary halogen headlights. Turn the lights on/off with the main switch and it stops.
Not got to the bottom of it yet.
