they look pretty badass, but i dont think they will do much in terms of lighting.
the light from LEDs emit bright light, but it doesnt carry very far.
imho, get them if you want them for looks, but dont go driving in fog..

it should work well for street driving but not highway. i think it should work in a very narrow light focus for 10-15ft.
Cosmetic wise, it looks nice.

Not sure about how many lumens it is going to produce and I think there are some TN members that know more about that.

If they are 5mm leds, to get a proper wide angle outa them, they qould only put out lik 1000Mcd which is practicaly nothing. LEDS are allmost there in terms of technology, and lumiLED is about to roll out with their DOT approved 5 watt luxeon bulbs for cars. But i don't think those will give you the proper optiks that u need. Not to mention that driving around with BLUE leds on is just screaming to be pulled over.

the lights would only be useful for being seen by other cars, not seeing...

I used to have LED lights for my bike and basically I used them for that purpose, to be seen, but not to see with. Bike has a lot less power than a car since those lights use 4 AA batteries in front, and 2 for the rear, but you get the idea.

i wouldnt trust the leds to light the way during times of need, kinda pricey, but they do look badazz

take a look at these:

http://cgi.ebay.com/ebaymotors/OPTI...TS-UNIVERSAL-NEW-IN-BOX_W0QQitemZ7987499137QQcategoryZ33716QQrdZ1QQcmdZViewItem

pretty good deal, think retail at other sites is $40

Just ordered some CATZ Multi-Surface Projector Gold Iridium Fogs for myself today too :D - $70 shipped
those looks nice.
not too suitable for gen4 cos of the shape.

good price.
looked elsewhere and it runs about 55$

******NOTE: Remember, if automanufacturers have not used it as standard equipment yet then i wouldn't rely on it. Two examples, HIDs and LED taillights. Once HIDs and LEDs taillights started to be used as standard factory equipment, then all the cheap stuff started to become marketed. If the major lighting companies such as Phillips, Sylvania, etc.; and car manufacturers; and LED technology companies (ie Luxeon) all have NOT been successful in effectively utilizing LEDs for headlights/driving purposes, how the hell did this company (and including PIAA) manage such a task? Simple answer, they couldn't/can't!

time to revive a thread
so im into retrofitting stuff
and ive thrown some ideas at a few buds of mine
I have found what is known as an SSC p4 or 7 (cant remember) led
its 900 lumens (rated by seoul) at about 10 watts or 2400ma
now what does this mean for fog/ headlight retrofits?
HEHEHEHEHEHEHEHE
it means GODLIKE!!!!!
thats right lets think about this, halogen headlights or fog lights? approx 1700 lumens MAX
so these little buggers, 2 = 20watts for 1800 lumens
thats more lumens than the standard halogen?
wanna keep going?
4 = 40 watts, and 3600 lumens!!!!!!!
thats again, (while 5 watts over) that HIDs (only philips brand HIDs are rated at that toooo) and WHITER
(as u get "whiter" or bluer light, u loose lumens, unless ur running leds, u gain LUMENS!)
now
the issue i have is the actual retrofit
room? in gen 4 camrys and gen 8 civics, i have no problem for room
my problem is spread and cut off
a) what the hell do i do to get the cut off necessary
b) lexus FAILED with their led headlights, and this would put out MORE lumens than theirs (each led on theirs is "400" lumens, but measured at less by an independent company, they have 5 leds per side, 3 in projectors, and 2 for side illumination, thats only 2000 lumens, not much more than halogen, why bother?)

what i need
a) a housing that will work with such leds, and provide sufficient heat sinking, cutoff, light output
b) someone to build the housing haha

ideas welcome, but the best idea i think is a projector
heres my ideas
Projector: great output, great cutoff, but hard to find the focal point, esp with 4 leds. Heat sinking MAY be a problem, but maybe not

Reflector housing: Your standard internal reflector housing, requires light to be pointed internally towards reflectors that will spread it.... big problems may arrise, including light output, spread and heat sinking

refractor system: What people like to call that PLASTIC light spreader in highpowered led systems. These generally have good spread but are hard to attempt cut offs with. heat sinking would be easy, light output would be great, cutoff would be mushy
hard part? design and building of such a plastic lens that would go RIGHT ON each led and shape its output!

I have 3 websites now i am asking this question., so far 8thcivic.com AND a physics thread website have posted and given info, but i still have no direct solution

there are some intelligent minds here, so i will let u guys mull over it and see if u know of a solution, OR know of someone who can make a system for us

the last, but best idea, is to just use those lexus headlights for the retrofit, but PRICE is UNBELIEVABLE!! for some plastic and glass!!!!

That's 1.6 to 2 times as much light as you'd get from a typical halogen headlight and about 2/3 that you'd get from a D2R bulb.
