which is better yellow or white fog bulb?

[red_one]

btw, i think the use of foglights in the metro is still illegal.

Reality is many are using foglights even without rain or fog. Drive at night and you will see many cars with foglights on here in Philippines.

yespo. and i find them, squint-able. nakakasilaw yung iba!

i used to have yellow fogs, many, many years ago. i found them a significant help in the rain , at night.
tinanggal ko, dahil "i could see the oncoming motorists, squinting". nakakahiya.

Well either reason is mahina na low beam or masyado malakkas hi so settle sa middle, foglighths on hehe

Yellow is still the best when you have to use it for foglights. By law, the ONLY lights that can use yellow are foglights and high beams. Di siya pwede pang low beam. I'm surprised that there are motorists na nasisilaw pa sa foglights considering that foglights are mostly placed at the lowest part of the vehicle. Naiintindihan ko pa kung masisilaw sila sa yellow na low beam. Sa high beam naman acceptable siya kasi rare mo naman magagamit ang high beam for extreme situations. Ang silbi ng foglights is to light up the path and not the vehicles in front of you.

I use 6000k hid on my yellow casing foglights. For me yellow light is better, they give contrast on foggy areas / roads. White just lights up the fog making it more difficult to drive. And i observed that it is better to turn off headlights and just use fog lights when fogs are very thick.

The reason why the fog lamps usually has lower kelvin rating than headlight its because 4000k and below cuts thru fog/rain better than the ones at the upper kelvin rating like 6000k and above na instead na kalsada ang makikita mo ay hina-highlight pa yung fog/rain so wala ka na makita sa daan. Lalo pa sa asphalt road, yung mga naka 6000k and above ay halos di na ma distinguish kung may puddle of water sa daan. This is also one of the reasons bakit night rally(even night road races) drivers use lower kelvin rating. Lower kelvin rating have better contrast.

Update ko lang po itong thread with additional info: Are Yellow Fog Lights Better? Discuss. [emoji74][emoji120][emoji594]

for ordinary everyday (every night!) driving,
if it is night time and there is fog, smoke or rain, yellow lights offer more useful illumination. but one must be mindful, because yellow lights offer tremendous glare to the oncoming motorist.
if it is a clear, smokeless, fog-less, rainless-night, white lights are fine.

let us also remember, that those maximum speed limits posted by the roadways, are for ideal daytime driving conditions only. at night or in poorer visibility conditions, it is common sense to go slower.

The typical color of a foggy condition is white, using yellow tinged light offers CONTRAST which is good for a low visibility scenario

if you want performance, i.e., cutting thru the rain and fog/smoke, go yellow.
it's on page one of this thread.

It doesn't have to be pure yellow. Warm colors between 2700-4100 Kelvin, give or take, can be used for fog lamps.

Any lower and you lose lumens as the light starts shifting to orange.

Any higher and the added blue light starts becoming a problem. Blue light will easily scatter in the atmosphere, including fog, dust, mist, rain, road debris, etc. So instead of seeing more of the road, you see more of the fog and every speck of flying debris. That's why the sky is blue.
