UPDATE: OK I got the vision LED and it's pretty good
The Vision LED, or the Xtreme Vision LED? Two different products; the Xtreme is the one worth trying. The (only) other LED worth trying is
this new one from Sylvania which I've seen a lot of good results with.
I am trying to get the original honda OEM bulb linked to originally but that is proving more difficult that it should be. I am unable to contact the Amazon seller and I am not sure that the bulb for sale in the ad is the one pictured and not a wedge fitting because they have it listed for models of Honda that do indeed take the wedge fitting.
For one thing, Amazon's parts application catalogs are a joke. For another, remember that vehicles in one market (such as the USA) often do not take the same bulbs in the same locations as the same-model vehicle in another market (such as Australia). You've got the genuine Honda part number and a link to buy it, so...buy it!
I have contacted three local honda dealerships in Australia and they are unable to locate the part number.
Correct, because that bulb is not used in the Australian market, only in the US and Japanese markets.
So I was wondering if anyone would happen to know who the original manufacturer might be, Philips, Osram, or Stanley?
Stanley.
I have found this NARVA bulb and I was wondering if it is likely to be as good as the Honda OEM, or even this HELLA brand?
No. It's a plain, ordinary P21/5w, just like your bike originally came with. And Hella doesn't make bulbs, they buy them and private-brand them, and quality is inconsistent-to-poor.
