I agree with the points below, and can definitely see why someone would want to stick with brighter incandescent bulbs.
I will disagree with this statement however. Neither LEDs nor the Malibus/Xenons are "viable projector light beams." If your goal truly is additional illumination in support of driving, you'd be much better served to buy real fog lights and fit them into the OEM fog lamp recess. The work recently done by yellowgizmo99 is a good example of a more "viable" lighting option.
