Fog Light Replacement (White)
 
Dear All,

I am new to this forum, I am seeking your help and advice.
At the moment i am waiting my 2012 Grand cherokee 2012 limited v8 5.7L to arrive.
I am considering to replace the standard fog light, with something that match the color of the head lights. However, i am not sure about the bulb size nor i am sure if i can just replace the blub with a white one and what brand i should order.

Your help i appreciate it.

Thank you!!!

youll need an h16 hid conversion kit. Send a PM to forum vendor "Xenondepot" They will hook you up with an easy to install kit

just have to be careful with HIDs, i had em on my truck and a couple weeks later i noticed the back housing was melting. wasn't to bad to fix $40 for new housings i went with LEDs after

any other option than the kit? something like just changing the bulb? i read in here about the Putco bulbs, but some says its fits loss. so i want a final call will they fit and give me that white look? or any LED ?
As the HID kit will be too complecated for a beginning like me.

Why do you want to replace them? Going with a second set of white lights in the foglights will totally eliminate their reason for existing - to help in foggy/bad weather situations. The more yellow light, combined with the shorter beam pattern, helps you see up close and be seen in bad weather situations. Going with a whiter light is not going to help, and will just serve to reduce your visibility.

If you really want to go ahead for it, you can probably find some "hyper white" bulbs. Unfortunately, the bulb used for the foglights is rather uncommon/strange, and so thee's limited options.

I hope I am not highjacking the thread, seems to be related.

Maybe someone here can chime in, but I was under the impression that yellow was no improvement over white fog lights. My limited research as follows:

Fog lights are low-mounted lights (bumper level or below) that project light that's cut off at the top. So the light pattern on a good-quality fog light goes straight out at bumper level and down, but not higher than that.

Fog tends to hover about 12 to 18 inches off the ground. So by projecting light in that fog-free pocket, you can illuminate the road a greater distance from your car and therefore see farther ahead. Some people swear by fog lights. Others claim that they don't really make much difference.

So the question becomes, to yellow or not to yellow? There's a lot of debate about this, but the research says that yellow lights are no better than white lights at penetrating fog. The theory bandied about was that yellow light has a longer wavelength and is therefore less likely to be reflected by the fog particles. Turns out, this is not true.

Any expert opinions on this subject?

I recall seeing a comparison in a magazine a few years back, the result from that was yellow makes no different at all and was tested to be slightly worse, stating light doesnt penetrate fog no matter what colour, it is the position and quality of the source, that is it has to go under the fog, hence fog lights sit low. Rally car engineers have done countless hours of testing on this topic with an endless supply of equipment and money and you never have or never will see any colour but white on the front of these very expensive and high tech machines. I know who i would follow.

my guess is that it isnt so much about the penetration factor but rather the amount of light reflected back at the driver and as such i would think yellow or amber does offer less reflectivity. i drive all night, every nite usually 7 days a week 400-600 miles per nite. and in real world use i will say that my dully d2s i have in amber are the best thing ive used yet in fog. ive had regular incandesant, yellow hids now the duallys

As i am living in an area that rarely get fogy, the reason i am looking for the change, is for the look and to match my head lights

I guess if yellow or amber was better than, the manufacturers would probably use them.

I'm no expert but I have a post on fog lights at http://www.jeepgarage.org/f190/fog-lights-41206.html that you might find interesting. The biggest take-home is that the standard PSAX24W fog light globe works much better with the Jeep's reflectors to give a low wide beam which as you say, is what one wants for fog. The LEDs give a diffuse beam. For this reason I went back to the standard globe. Regarding wavelengths, if one looks at bushfire smoke at a distance, with the sun behind you, the smoke looks blue and with the sun in front, it looks orange. This implies that shorter wavelengths (blue) are more easily reflected and longer wavelength (orange) penetrate more so orange should be better in fog. Whether the difference is significant driving in fog, I can't say.
