Ram 2005 headlight bulbs
On the new to me 05 Ram 2500 CTD, I note a big difference in lighting compared to Old Faithful (97 Ram), but it's still not perfect. What type of bulb should I use while staying street legal? I've use...

No real "smoking gun" on this subject.. But many of the places I have looked at seem to agree with my observations that the blue tinted bulbs tend to not improve but may reduce your night vision. I have not been able to find any "evidence" that 5000K and up "improves" your night vision as of yet..
There are ways to achieve 4000k+ color temps without tinting the bulb. I did a quick search and found only anecdotal evidence that suggests color temps in the range of sunlight (4000-6000k) are "best". That's why I wondered why someone said 3200-3500k is best for nighttime performance. I haven't run across anything that suggests that range is ideal, but am open to supporting scientific evidence.
I've read a lot on Daniel Stern's site and used two of his recommended products (Nightbreakers and X-treme Vision) based upon his information. While I agree with much of his opinion, some of the evidence that he presents is anecdotal but he applies it to a broader scope of products. Some of that is common in this thread. There are a lot of poor products on the market today. However, there are ways to improve light output and performance for halogen bulbs without negatively influencing every other person on the road.
