I did a search and found mostly information on people that are trying to upgrade to fog lights because they don't have them. I am interested in fixing a burned out fog light on my 99 4runner and I am having a hard time finding out what I need.

Sylvania's website offered this as an answer:
Fog/Driving light
H3-55W
H3ST Silverstar High Performance Lighting: the whitest and brightest Halogen

I will climb under my truck later today to see if I can remove a bulb. Has anyone fixed a burned out fog light on a 99 4runner and if so could you offer any tips?

 

You might find that the reason your fog light is out is because corrosion has destroyed the poorly designed Hella's that come from the factory. If that is a case do a search for hella fog lights and you will find quite a bit of info (or check out this thread linky ). If your fog light is simply burnt out you should be able to replace the bulb with those H3 Silverstars (although I prefer the 100w H3 Silverstars, and I would replace both while you are at it). All you have to do is remove the bolt holding the fog to the bracket, pull off the rubber covering to expose the bulb, and swap out the bulb. There is a write-up out there somewhere on how to do this, but I cant find it yet.

 

If you're referring to the stock OEM foglights, I believe they are the Hella Micro DE's which I have on my '00. The standard bulb for that is an H3, 55 watt. I replaced mine with Hella Yellowstars which provide additional contrast in fog and rain over the whiter standard bulb. Are you using your foglights for their intended purpose or just for asethetics? Silverstars in your foglights are too "white" for reducing glare in fog and rain (IMHO) but would suffice if you're simply using your fogs as running lights. Be aware that the Hella Micro DE's have a short, wide beam pattern (which a true fog light should) and will not satisy you as a dedicated driving light (which has a longer, more narrow beam pattern).

Also, be aware that bulbs higher than 55w in the Micro DE may cause overheating and damage. The lamp assembly is small and does not dissipate heat as well as a larger lamp assembly.

 

I have the Silverstars in mine and yes,they don't help out in the wet but I'm going to color the lenses yellow and that should make a world of difference. The Silverstar fogs do actually outshine the OEM bulbs by quite a bit and you can actually tell theri on.

 

Very validating, thanks. What method are you going to use to color the lens? Is it proven to be compatible with the heat from the bulb? I'd be interested to hear how it fares since I'm a big advocate of fog lights being toward the "warmer" end of the spectrum to truly help in night fog and rain.

 

I had to replace one of my fog lights, and i just picked up the 55w halogen from autozone, and it was the biggest bitch getting the wire out of the current fog light... but after that it was a breeze... had to tear apart that protective shielding though... Anyways the light works great now...

 

I like the stock look of the fog lights because it puts a nice balloon of light right in front of the truck. I'm running Xenon's in the regular lights so the light output for down the road isn't an issue. So it would seem I need to locate a 55w H3 bulb, or two as changing both was recommended.

On a side note. How come sometimes I see my main headlights listed as H4's and other times I see them listed as 9003's?

Oh and thanks for the tips and info :beer:

 

9003 = H4's...just depends on where in the world you live.

 

I kinda figured that was going to be the reply. It would have been hard to figure any other way. Thanks for the clarification.

 

Well I did get them changed. I used the Sylvania 100w bulbs. Hopefully they don't get too warm. I had the units with the bottom cap not the rubber boot. Thank you all for the awesome information.

 

Well almost one month later the fuse for the fog lights blew so I removed the 100w bulbs and installed new 55w bulbs.

 

hey you could always throw in a couple new wires, another fuse and a relay for the 100's email me if you want a quick dia i made for a friend

 

I'd stick with the 55w...the 100's really do make a ton of heat. I just burned out a pair of PIAA GTX (Only available in Japan....) because they got too hot. Figures.

 

I really hate PIAA. I had a set of the PIAA Ion Crystal bulbs in my fogs, and both burned out one day after the other, after being used for only six months. Many other people, including you too, have burned out PIAA bulbs prematurely. I will never use PIAA bulbs again, they are overpriced rice.

 

I just bought cheapie Nokya H4 Yellow bulbs off of Ebay and so far I really like mine.
