Today I installed another BA9S-G4-32-12V in the neutral indicator lamp. What a difference! It now works like it should have when new. Even in daylight, it shows up in peripheral vision. I no longer have to lean forward and look down to see if I am in neutral.
I also installed a pair of BA9S-W-90-12V in the small lights on either side3 of the speedometer-headlamp unit. They went from dim yellow to bright white. From in front of the bike with the tribar headlamp on low or dim, these are much brighter and whiter than the headlamp. They are smaller and actually put out much less light than the headlamp, but as a point of light, they are much brighter. GA-DK
