Ok, let me chime in. I run the vnl series Volvo. I also
Replacace/about to, my so called clear forlight bulbs with 3000k hid. So, please, do not be blinding me from behind or you'll see what hid fog and head lights look like. Plus, I have 4 hella off road light on top and behind of my bunk 55w each - projector.
Now, white lights do not do that much good in the rain, snow, fog, you need yellow. Yellow gives you more lumens and they are brighter. - 3000k hid. Baby. I sell them too. 3 year warranty for headlight hid or foglight.
