The high beam indicator hasn't worked for some time and still doesn't work. Do you have an idea why that might be?

In the schematic above and the wiring diagram below you will note a 4-wire splice labeled S235. We know the wire between the splice and the left headlamp is good because it was delivering the leakage current from the right headlamp fuse (through the DRL diode) to make the left headlamp glow dimly. The break in the wire is somewhere in the green highlighted wire between the splice and the fuse. That part of the wire also supplies battery voltage to the high beam indicator. When you jumpered around the break in the wire, you jumered around the high beam indicator battery supply voltage. Based on the fact that the high beam indicator has not worked in some time, I'm inclined to believe the 4-way splice may be the common source of both problems. I suspect the high beam indicator wire wiggled loose from the splice earlier and the wire from the fuse came loose recently (killing your headlight). If you were to trace out the wiring harness until you found the splice, you may be able to repair the high beam indicator and the headlamp problem. If the splice is the problem, fix it and you can remove the temporary jumper you installed.
