With my cheapie light meter
Stock OEM Bulb: 40,000 Lux
New PIAA: 63,000 lux
Slight blue tint but far less artifacts than OEM lamp. I like the more consistent and full beam.

This this is so much better than the 3 stock style horns I've killed that there really is no comparison.

Not worth the money, the HO bulb from my local Harley dealer was almost half the price and very comparable to this bulb, its just not purple on dim and as white on high.

This flat works better than OEM.

I was very happy with the out come of this product.
Much brighter than stock, also they seem to have a greater distance of projection.
I would highly recommend this light .
