Are the Putco bulbs actually functional in terms of better visibility in fog or low visibility, or is just more for aesthetics? I was considering changing my white fogs on my 97 LS400 to yellow, because A. I love yellow foglights and B. I feel like yellow lights cut threw the fog better than white.
A yellow light does in fact cut through dense fog more effectively than a whiter light. Yellow emits at a lower frequency than whiter light therefore cutting through the fog much better. This is why when you turn on your brights when driving through fog it only exacerbates the problem giving you a massive glare on the road ahead. It's not only an aesthetic upgrade to go to yellow but a functional one as well. A wise investment.

hey guys im new to this thread...i have a 2011 IS350 n need some advice to which fog light bulbs i should buy. I want them to be really yellow and some ppl told me i should go with HID but its too expensive. I have read the previous posts stating that putco yellow are really good. How are they compared to PIA or Nokya yellow?
