You can easily overcome that aesthetic short-coming by switching to
Cibie lamps.

I have also read that the dilation/contraction reflex of the eye is
relatively uneffected by blue/bluer light. That's one reason the
"blue" lights appear brighter; the pupil fails to contract. I know
the PIAA lamps are not the trendy blue lights, which are simply
tinted bulbs, or low voltage filaments being over-driven.
I've been a big fan of Cibie lamps since I started rallying 25+ years
ago. Most of the difference between good and bad lights is the lens.
Poor beam control cannot be overcome with higher output bulbs. Cibie
pioneered the quartz halogen lamp years ago and still make a quality
product.
