Yellow Fog Lights

Ladies and Gentlemen,

I was hoping to get some insight, recommendations, guidance on going about changing my Fog Lights to Yellow. Should I do the yellow film, yellow bulbs or go all out for yellow housings? If you make a recommendation please list your reason and a quality product to support your claim.

Winter in Michigan is right around the corner and fog and snow will be an issue. I have read the yellow increases visibility so that I why I am leaning in that direction. Thanks in advance.

 

I'd go with Nokya yellow bulbs. I've had them and had great luck with them. Right now, I'm running OEM fogs that have been spray tinted and clear coated with yellow bulbs. The only reason I would tint or apply a film to the fog light itself would be if you wanted that look when they're off. Otherwise, the yellow tinted bulbs are fine.

 

I have bulbs, I can't say I've had experience other ways but here are some pros and cons plus some things I've heard:

Pros
Easy to change back if wanted
I've heard laminates can melt to the housing, no melting with bulbs
Yellow look
I've heard, you don't lose as much light output as you would with a laminate

Cons
Not always yellow, meaning when theyee off, the look normal
Not as deep of yellow, very light and from some angles you can't tell


I am happy with my bulbs, but wish they were more yellow, and wish you could tell they were yellow when off. (I do believe you can get more yellow bulbs, but either light output or price become issues)

 

I have the Nokya yellow bulbs in my fogs...they've been in there for about a year and i did the anytime fog mod so they are always on. They haven't faded or burnt out so im happy with them so far.

 

I have yellow bulbs from http://autolumination.com/headlights.htm. They don't put out a deep yellow color like yellow lenses would, but they are definitely yellow when compared to the headlights. And when they are off, the fogs look stock. I'm happy with them.

 

I used a tinted glass spray and it came out awesome. I like how they are yellow with the lights off.

 

I have the vinyl overlays. They have been on for about 4 years and holding up great.

 

Hella Yellowstars are amazing.
Ive been using them for years on all of my cars/trucks.
The trouble lies in actually finding them.
I forgot what website I found them on last year in the taco's size. It might have been Amazon.

 

I did the same, paint them so you can spray them to how deep you want the yellow.

 

Did you guys pull the fogs all the way off of the truck to use the glass spray or just tape the bumper off? Also, did you need to prep the surface or just clean really well and start spraying? Thanks

 

I did the tint spray. Remove the fogs. It's not that hard. Trying to mask while the fogs are in the bumper is a PITA.

 

^^This^^

I've been running the same bulb for 4-5 months with no issues. Picture of them on is in my build page. I'm on my phone and too lazy to link it.

 

When you remount the fogs is it a pain in the ass to adjust them. Please excuse my ignorance as I am usually too much of a sissy to do a lot of modifying in fear that I will mess it up and pay more money to get it fixed.

 

This is a copy and paste, not my words.

There are several scientific studies out there that say it is an old wives' tale that yellow fog lights give you greater visibility over white or blue ones. Many of the studies are from coastal and mountainous regions of North America and Europe where fog is much more prevalent. The premise of the wives' tale, that yellow light waves are long enough to pass through water particles without reflecting back to the light source, is based on a misinterpretation of Lord Rayleigh's principle of light scattering (search for "Rayleigh scattering" or "why is the sky blue").

As it turns out in all the published studies, the water particles in fog and road mist are entirely too large to not reflect light waves back toward fog lights, be they yellow, white, blue or even green. The studies show any fog light that is properly mounted and aimed is effective, as the reflective angle of larger water droplets tends to be directed back toward the source of light than scattered away. The idea being that an effective fog lamp has to be a low mounted, wide dispersion light that gets as far under fog and mist as possible, so as not to be directed back toward the driver's eyes. This is why driving in fog with your high beams on is a bad idea - i.e., the reflective angle of your headlights/high beams is too close to the same elevation as your eyes to not be reflected back to you, thus blinding you with reflective glare.

So, why do yellow fog lamps seem to work better? It's because of the way the human eye interacts with different colors of light. Blue and violet are very difficult for the human optical system to process correctly. They are the shortest visible wavelengths and tend to focus in front of our eyes' retina, rather than on it. The further a light gets from the red end of the color spectrum, the bluer it gets. See any HID color temperature chart for proof.

 

If you get Nokya's, make sure you replace the shit rubber O-ring they use at the base with ones from your factory fog lights. Nokya's use such flimsy rubber that it's almost like a rubber band, eventually water will get into your housings.

Don't use Lamin-X film on your housings either. I did that route as well and it retained so much heat in the housings that both lenses had many small cracks. Looked like shit.

 

Yes, I've recently experienced the o-ring failure.

 

Very easy, there is one screw to turn, but they probably won't even need it.

 

I did not need to adjust mine after taking them out, there is an adjuster screw and as long as you don't mess with that it should reinstall level as when you took them out.
Also if you do spray be sure to do super light coats so you can control how yellow you want them. It is super easy and can be done in a matter of hours.
Be sure to clean the lens before painting, and I would recommend taping around the lens to avoid any over spray on the housing ( I don't think it would do anything but I am a perfectionist.)

 

I have the Headlight Armor vinyl and never had any issues. I run my fog lights all the time.

I have some eBay yellow bulbs combined with yellow vinyl overlay .
Gives a nice yellow color .
The vinyl is a pain to work with I'd try spray next time .
