been looking at new headlights and bulbs. i was wondering if anyone used led lights for headlights. i see that thay use them for daytime running lights and most of them come from china...i do know the differance between the 5050 smd leds and 3528 smd leds and the temp. is between 5500k and 6500k. so any info on this would be helpful and thanks for your help

it wont work

Not that this matters to most people but they are illegal, Even Audi cant use them in the R8. There is an old law stating that all headlights need to have a high and low beam.

On top of that LED's have only recently gotten to the point where they are good enough to use for headlights, so they will either be very expensive or absolute garbage.
You'll notice the sellers stating "these lights are for show purposes only, not for road use".

what law states low and high beam? most factory hid lights only have one beam

F22Master

Doesnt matter. All EF's come with separate high and low beam bulbs. If you replace the low beam with an LED bulb, you still have a separate high beam bulb.

LED cheapos will not produce any light visible for driving at night.

swordofdoom what do you mean by any light visible for driving at night...lumens...kalveens...watts...ect.

Retro fitting won't work.
Similar to replacing a stock light bulb with HID doesn't work.

The reflector and lens need to be designed for the bulb in order to work correctly.

Here is a LED headlamp that is DOT legal
since 2009 -

4dref, i went from stock headlights to projector headlights with h1 type bulbs that are 7500k and 100 watts... now im going from that to projector headlights with 9005 type bulbs... the bulb type im looking at are 120 led 3528 smd 9005

ajjct

just got the info on how many lumens that the led lights put out, it is about 500/600 lumens. also has 120 led's, type 3528 smd, 5500k / 6500k.
still have to test to see if it will work.
thay may take up to a month to get here, thay are coming from hong kong.

500 or 600 lumens is crap halogens put out something over 1000 lumens and HIDs (if in the correct housings) put out over 2,000 lumens so really leds are a waste of your time and money, however you could probably retrofit them into nice looking DRLs or fog lights

ajjct

red-rocket you may be right, but i only spent 17 bucks, it wont hurt me that much...
for fog lights i've got 20 leds each side and thay are bright at about 6500k / 7000k you do see alot with them and only spent 14 $....thanks for the info

ok gotten the led light's one problem the bulbs are to big for the hole's in the headlights...ok two things can be done,...one, make holes bigger to fit the bulbs, but may mess up the projector headlights,..or..two, get the next size smaller in led's which is 102 led 9005 type bulb...thank you all for your help and info.

the only thing I can think of which is even close, are the new LED aircraft landing light bulbs, but they are round lamps like the 5 1/4 sealed beams, in the old days when cars had four round headlights, it was common to put incandescent landing light bulbs in, if you had an old car with four round lamps, and a lot of money to burn, sure they would drop in, but you need several grand for the lamps,if I remember right the old sealed beam landing lamps are based off of car headlamp size

lostforawhile

they have actually gone down a lot in price, I'm suprised, I believe these are the same white wheelens they use on emergency vehicles, http://www.skysupplyusa.com/whelen-p...FUHe4AodmTgAFQ

i have a old set of projector headlights,..thay are made for h1 bulbs that i can mess with the halo ring doesnt work on it and the adjusters are broken....that will be my next step..wont cost me anything but time and fixing it...still may buy the 102 led lights and see if thay fit

ajjct

lostforawhile,..thanks for the info and link,..but im not going to spend 600.00 for a pair of landing lights (only) then have to make up a compleat housing unit for it...to much work and money...but thank you for your help.

ok back to my converion of my old projector lights (h1 bulb set). well after looking them over and taking it all a part...to cut the holes bigger to fit 9005 type bulbs wood take a lot of work and to make the holders for the lights..so i ordered a set of led h1 bulbs to see if (1) thay will fit in without any cutting and be done with it. or (2) have to cut a little to make them fit...i also desided to cut the units up and make a pair of home made fog lights out of them...now im waitting for the lights (bulbs) to show up...after that i will see were i can mount them on the car...by the way the low beem side has a heavy glass len (domed) that can be flipped a round to make it flat if needed, also depending on how you like to see them, you got (2) ways you can mount them all most flat (sticks out about half inch) or sticking out about 2.25 inchs...make sure which one you want the cuts are difforrent.

LEDS are great for signals/markers, but I think they are worthless for driving beams. Anything that works will be too large and illegal. HIDs are not the answer but they would be a better choice. Good luck with your project.

zrickety...hid arnt wouth the money,.. oem's are to low on the light sperktrum (3000k-4500k) thats in the yellow zone....what im running right now are great thay are in the pure white zone (6500k-7500k)...i just wanted to see what if any (led lights) where out thair and thay are but i've been fineing out that thay are just a littel to big to fit in the holes so you have to make some adjustments to the houseing (cutting or grinding). the base are fine and work like thay should its the bulb part that doesnt fit of the led's...and everyone around here knows when im buored i start to think of sruff to make and try which this is one of them... and thanks.
