What's the difference between H11 and 9006?

Hey guys. Is there a difference between a H11 bulb and a 9006 bulb size? Are they one in the same?

If the car takes a "H11" will a "9006" fit?

I'm trying to replace my halogen fog lights with yellow. The manual states 9006 and so do online sites, but someone on a lexus forum mentioned it was an H11 not a 9006.

I just want to make sure i order the right bulbs. The fog lights are projectors.

Thanks!

No, they're not the same thing. They're very close in size, but the base is different. Namely, 9006 has bulb > rubber seal > locking tabs > connector, while the H11 has bulb > locking tabs > rubber seal > connector.

The filaments are very similar, but I think H11 is a newer design.

thanks

My guess is that it's 9006 - I know the Lexus projectors have taken 9006 and H3 in the past.

Whereas, H11 is usually used in low-beam projectors, or in reflector fogs.

Do you have any pics of the bulb, or is it in a location where it's a major PITA to get to?

I googled it and got a good post about HID fogs on a lexus forum... then I see that you posted in it too

According to the Sylvania bulb guide, it's a 9006 in the foglight.

The RX400h with halogen headlights uses H11 projectors in the lowbeams (which is almost certainly the Stanley MDX projector, since it's almost identical to the RX330), so that's probably why the guy on the forum is confused.

BTW, cduluk, I put ebay clear lenses in my M35s, and I got this funky cutoff.

The lens needs to be closer to the shield, but it's in as far as it will go without chopping up the lens holder, which I don't want to do.

nalc, what type of clear lens are you using? The problem is that the lens' focal length just doesn't work with that projector. If you move it closer, the center will be flat and sharp, but the outer edges will be all blurry. Can't have both, unless the lens has the right curvature..

Well, i've confirmed that the rx400h fog lights take H11 NOT 9006.

No idea how every online manual and car's manual can be wrong, but they are lol.

I got a pair of the PIAA Ion Yellow H11 bulbs from a local car store for ~$70 bucks. They look GREAT!

Clear lens from ebay H3 projectors that I ground down the outside to fit.

The cutoff would be great if I could move the lens like 1/8th of an inch closer to the bowl, but it's as close as the lens holder will let me move it.

If I run spacers, the whole thing is blurry. As I slowly move the lens closer, it gets sharper and sharper. It would look perfect if it got a little bit closer, but I don't want to chop up the lens holder on my $$ projectors just to make these lenses fit, when I could just buy a pair that does fit.

What lenses did you use in yours? TSX-R?

[gearbox]

for future reference, they are totally different. if you have 9006 and want more light, you can modify a 9005 bulb to fit. if you have H11 and you want more light, you can modify an H9 bulb to fit. 9005 and H9 are hi beam bulbs around 65w and put out almost double the light output when compared to the lo beam 9006 and H11 bulbs. and by modify i mean you only shave a small amount of material from the bulb tabs. no modification to the housing.

but glad you got it figured out. H11 is one of the dimmer halogen bulbs, just a tiny bit better than H4. and they look great in yellow.

Eh, i get enough light from the H11's i'll let it go lol.

Nalc, i honestly don't remember what lenses i used on the M45's, it was almost a year ago. It wasn't the tsx-r lenses though i know that.

Search for it. Try to find my earliest posts (that's when i joined the forum) i typed it somewhere... lol

The lenses you're using will never give you good output. The curvature's off. If you get the lens closer, the center cutoff might be sharp, but the outer cutoff will get VERY blurry at larger distances. Just won't work =/

Do a search for whatever lenses i used, they were perfect.
