What is the visability on these, or is it just for strickly color? I am thinking about swaping out my 8000k to 10000 or 12000. I would be great to know if it is possible to run high intensity on the lower aux lights, and what kelvin i need to produce the IS300 lower aux light yellow. 2006xa

 

If you want a yellow, then you should go with a lower K. Usually, 10,000 or 12,000 K is made for color. Light output is dramatically decreased when you go that high up.

 

This site has some good pictures showing the temp and color it produces. The lowest they go though it 5000k.
