High beam is rather bright in comparison.
But you are right, as the thing flickers brighter every now and again, i suspect a poor earth or duff connection.
I will be stripping the lights out and putting a meter across to see the voltage and how it compares to the battery.
Next will be the switch itself, maybe a clean of the contacts.
Failing that - a new bulb and try to demist the inside of the lamp itself (looks like a big bowl of fog inside there)
Tis funny though, it has only done this since the following on a recent trip
riding with lights on - no revcounter and temp guage off the scale, also no indicators or horn or headlamp.
Turn off lights, and rev counter and temp came back - still no indicators or headlamp
Never found the problem as i just lifted the seat unit give it all a wiggle (technical term - for fooked about with stuff i have no idea about) and it all came back !!!
Put money it's all related though
It also charges well, so can rule out the rectifier
