Good RLUs gone bad?

[xjwmx]

Anybody ever hear of a Reserve Lighting Unit going bad and turning a good headlight off?

I'm weighing these possibilities:

1. Having a an RLU fail and turn off a good headlight such that I can't turn it back on.

2. Bypassing the RLU but being able to switch manually to the other filament when the one in use inevitably burns out, but with the overhead of a few seconds of utter confusion.

Considering the worst case - failure in the middle of a curve. At night of course.

Never had an RLU go bad but the resistor under the tank that sends the lower voltage to the high beam if the low burns out was completely toast on my bike. It fell apart when I touched it. I removed the whole system a long time ago.

I think the cure was worse than the problem. Unless you are in restore mode, scrap the reserve lighting unit.
