I have always wondered how effective these lights are for night driving. I can't imagine a 5 hour ride at night when the lights constantly vary in intensity.
They don't pulse at night. In fact the pulsing light is the High Beam and there is a light sensor to shut off the pulse at night. If you flip to Low Beam it will be normal Head Light even during the day.
I've spent most my money on Motorcycles and Women, the rest I just wasted.
