I was not content with the light output of the stock H4 headlight on the CB1100 and have seen great reviews on the JW Speaker Evo 2 headlight. I realize that this light isn't super popular with the retro-look diehards but for me headlight output is a form-follows-function item.
The light is currently $265 on Amazon:

Installation was not possible using the stock bucket without fabrication or modification of the stock parts which I didn't want to do as I wanted the option to go back to stock. I ordered the following bucket:
The bucket is currently $55 on Amazon:

Installation was very easy. The hardest part was fitting the stock wiring in the aftermarket bucket as it's slightly smaller than stock. I've seen another post on here where the person used a much more expensive Triumph bucket and that would work well also.
Stock light and trim ring won't work with the JW Speaker light:

I'm still waiting for nightfall to complete alignment and get an idea of the difference.
There are tons of comparison threads online of these lights versus an H4 but honestly digital photographs of light output comparisons are pointless because digital cameras automatically adjust for available light, so I don't trust them as a final judgement.
