Interesting. I wonder what I did differently. Mine's a '96 Prado TX, wouldn't expect a wiring harness difference in one year of essentially the same vehicle. When I removed the harness and went back to factory wiring, the headlights got noticeably brighter, and now don't leave the low beam filament on with the high beams.Yes, used the harness. All appears to be working properly.
High beam indicator should be plenty bright.
