Inverted Highbeam...?

From post #1

- Low and high beams functionas they should, by which I mean they come on when switched at the left control.
- Low beam is aimed correctly, lights the road up well.
- High beam is tighter pattern, brighter light, but aimed much closer to the front wheel.

... And I didn't test it ... because I didn't think it COULD be what's wrong. My reasoning:

- Low on the control switch activates a nice wide beam, aka Low beam.
- High on the switch changes it to a tight, bright beam, aka High beam.

Looks and functions totally normally, with one odd twist: High Beam is lower than Low beam, aim-wise. Much closer to front tire. But bulb isn't in upside down.

From post #14

Low beam is exactly where it should be. Lights up the road pretty well, good spread, not in peoples eyes. Perfect. High beam is much tighter, therefor much brighter, and about half the distance from the front tire .... ie, way too low. Switch isn't backwards -- pushing down for the marked "Low" position activates the low beam mentioned above. Going up to "High" activates the high beam described above (much lower aim than Low beam). Bulb is not in upside down.

And yes, Steve is urging me to go make sure the wiring is correct.

I see a lot of finger-poking at the high-low switch and the computer keyboard over the last week, what did your test light show?

It would take less time to do the test than it does to reply to someone, explaining why you don't think that could be wrong.

Post #6, #15 and #7. I have personally dropped a sealed beam in a box without it breaking. How do you know the same didn't happen before you ever got the sealed beam? Trying another one is the only way to know for sure.

Is it a sealed beam (the whole glass headlamp is one unit) or a headlamp with a replaceable H4/9003 bulb?

Reviewing this thread, the situation is unclear.


The Magic GS-Ball says:
"Reply hazy. Try again."

"Sealed beam bulb is in correctly, not upside down. Text on the fresnel lens is not upside down." (Post #1") The same would apply to a H-4 bulb. Much more likely not to show damage if dropped in the box, but easier to see alignment of any small reflectors involved in the construction.

I once had an H4 headlight assy. that the bulb mounting boss in the back was loose. I could spin the bulb around 360°.

Yep lots of strange things can happen is this Mad Mad Mad Mad Mad world we live in.
