Biggest problem with the Bonnie light is the lens, not the bulb. Last year I upgraded my lens to a quality Cibie unit from
Daniel Stern Lighting.
What a difference! The OEM lens is ridiculous by comparison, the Chinese manufacturer clearly has no idea how to design a functional headlamp.
With all the regulations on modern vehicles it amazes me that you can get away with selling a stock headlamp that's that bad.
