Is H16 a new bulb type? Should I be able to get it at my local autozone or will I have to order online? The few I found online are all over the place in terms of price...

The Philips LED bulb I put in my fogs were h11 / h16 / h8. I also plugged those into my low beams and they fit fine. so I'd say go for h11's if you can't find h16's

You could always go the an auto parts store, see what their book says (either h11 or h16) and install it in their parking lot. If it doesn't fit just return it for the other one.

I think the main difference between h11 and h16 bulbs is the output. H11 being brighter than h16 bulbs. (I'm not 100% sure on this, and if someone corrects me I'll remove this)

Very timely post. I ordered low beam H11's from Xenon Depot and the package I received said they were for fogs. They fit great in my low beam sockets and the vehicle search indicated they could be used for low beams as well. Sounds like I am all set?

@rpontbriand the low beams in the 5th Gen T4Rs are H11, which is a type of bulb. I'm sure there are cars out there that use the H11 bulb in their OEM fog lights- the packaging for the bulbs is just packaging.

If you plugged an H11 bulb into your low beam spot (it wouldn't have fit perfectly if it was a different type of bulb), you're good to go.

Oh ok. So I am doing the H9 mod to my low beams which means I can use the existing H11 low beam bulbs and put them in the fog location and be set? If so that will save me some time and money which is always bueno

I haven't seen anything that suggests putting the H11 bulb in the fog housing. My understanding of the fog light housings is that they are not shielded / projected as the low beams are and thus they still require a dedicated and properly aimed fog light bulb (H16) so as not to blind oncoming drivers.

Someone please correct me if I'm wrong but I believe if you plan to use your fogs consistently on-road, you'll want to stay with a fog bulb.

Crap. This is why I am confused

The H11 might be the same fitment as an H16 but it's a far brighter bulb. The fog housing, as I mentioned, isn't "shielded" (doesn't have a cutoff) like the low beam projector housings do. So you'd be exposing oncoming drivers to a far brighter direct light from your fogs than you would normally.

I ran into this some time back.

Discussed here as well: 2014 Headlight Bulbs

People want to run H11's in their fog light sockets. Although they may "fit", the bulbs are definitely different.
The Osram H16 is a 19 Watt bulb, IIRC 790+- lumens, intended for the newer 4Runner fog lights. These are different than the non Osram H16's!
Some even refer to the bulbs as a H16 (Type 2).
There has definitely been some confusion for a while on this.
See this article: Even Osram Makes Mistakes: H16 Mixed Up with H11 | iJDMTOY Blog For Automotive Lighting

The H11 is a 55 Watt bulb and is not really intended to go into the later model fog light assemblies as they were in the earlier 4Runners.

[jdtaylor42]

Thanks a bunch for the replies! I know I can't be the only one confused by this. So I need to search and find "Osram H16" bulbs I guess. I definitely don't want to blind other drivers as I pretty much always have my fogs on when my lights are on.

The following is not intended in any way to be a commentary on other people's actions / mods but rather a way to explain my own feelings and reasoning behind installing and then UNinstalling an HID kit in my T4R's halogen projectors.

One of the first things I attempted to upgrade in my rig, and the initial impetus behind all my information gathering in this thread, was to install a Philips 4300k HID kit in my low beams. I was pumped to take on my first "mod", and really excited by all the positive reviews I read all over the forum about how much better the light was, how easy it was to do, etc... I admit up front that I pulled the trigger on the kit without fully understanding the implications behind placing HID bulbs in a halogen projector housing.

As soon as I did it I started getting brighted by oncoming vehicles, something that had never happened before with the halogen bulbs. I figured, okay, it's probably the aiming. I aimed the lights lower. It helped, but I still got brighted probably once every couple of days and it really cut down on the utility of having brighter headlights since they couldn't "project" as far. I do a lot of driving in the pre-dawn and post-dusk hours on two-lane country roads, which is actually one of the reasons I was so excited about the upgrade. However in retrospect, this is probably one of the reasons why I may have been getting brighted more than your typical "I put HIDs in my halogen projectors" person in a city / highway scenario with more ambient lighting from streetlights, etc.

In any case, after playing with the aim for a week or so, I also had my wife drive past me (in a Honda Odyssey, not exactly a low-to-the-ground car either) and get her opinion. I also got behind the wheel of her van and took a look for myself. Them f**ckers are BRIGHT, man. I also did way more due diligence with looking into what the right thing to do when putting HIDs in your vehicle: HID projectors.

Long story short, I've now spent time on the phone with many of the vendors I list in this thread to try to avoid wasting the $150 I spent on the HID kit by finding a true HID projector to retrofit with. My T4R is also my DD, so I'm not pulling off the headlights for a few days to do the retrofit myself even if I did have hundreds more dollars to spend on it. I'm pissed at myself that I pulled the trigger so fast, but I guess it could always be worse than having to eat $150.

Your mileage may vary. Just my experience, trying to do the right thing.

Honestly, very big of you to step into the other drivers' shoes, see for yourself, and accept the results. Most people are happy enough to say that "everyone else does it and says it's fine, so I'm fine too". Glad to see someone prove me wrong.

I'm all for enhancing the lighting, but not at the expense of someone else's vision. Technically, a "retrofit" (swapping HID projectors/bulbs/ballasts into another headlight) is still illegal. But it's only illegal in the sense that it is not DOT approved in the new headlight unit rather than unsafely creating excess glare and bothering other drivers.

So what's the new setup going to look like? Mini H1 7.0?

Haha. For now it's going to look exactly like putting the OEM bulbs back in and sealing the dust cover holes I created with duct tape on both sides. Toyota dealer wants $22 apiece for new covers, sheesh, rub salt in my wounds.

Thanks for the kind words man. I'm gonna try some Osram Nightbreakers and see if I can't get at least a little better yet more controlled light from the LBs.

EDIT: anyone wanna buy a very slightly used XD Philips 4300k kit? Haha.

Probably not so many "drivers/builders" think like OP (have it proved on my daily commute). Every day I see so many cars and trucks with stock headlights "upgraded" by 5000+K bulbs (either LED or HID). The worst are guys in very old trucks and cars that have headlights without any cut-off.

I think this way: if my headlights are blinding the guy coming at me, he can't even see where he is going and can easy jump to my lane without knowing it. I'm big fan of LED technology, but I drive all my cars with good quality (OSRAM or Philips) halogen bulbs in headlights.

BTW I have 2012 T4R (no projectors) so I would have to have a big scar on my brain to put HID or LED in these. Unless someone designs a dedicated LED or HID headlight (I mean the whole headlight, not just a bulb) I'm stuck with Mr. Edison's technology.

Anyone have experience with Sylvania ZEVO LED replacements???

I'm contemplating using their 1157R (R=Red) for the jury rig rear fog.

They are readily available in my area. Three different named auto parts stores carry only them and they are available at WalMart as well. Can't find any JDMs except on line.

Unfortunately no manufacture has "stepped up" to design replacement projector headlight assemblies to this point , but there is a solution..........

For 2010-13 models this is the only CORRECT WAY to add HID's, IMO @philsey did it right!
