E85 H7 adaptor for LED bulbs

Hi all, I'm trying to fit LED bulbs to my OEM z4 headlights but have come across an obstacle, there doesn't seem to be an Adaptor available for the LED bulbs that fits the OEM socket, I've tried a HID adaptor but that didn't work either, has anyone fitted LED bulbs with fans in the OEM lights successfully ??
Cheers Dave
 
why would you want to do this? you will get an error saying your lights aren't working unless they have a resistor in place. said resistor then negates any saving in "energy". completely pointless IMO.

they are also usually very dull compared to decent headlights from phillips. i'd rather have the safety of decent lights on unlit roads.
 
Sorry but your wrong, if you code out the voltage check you get no errors and no resistor or canbus device is needed, I know this because I have fitted the bulbs and tried them jut can't fit them to the headlights yet, and I want to do it because I can, thanks for your input however in accurate it is in addition the latest generation of LED bulbs or luminaries are rated at 4000 Lm per unit, I have Philips high power halogens fitted in my lights at the moment 100% brighter in dipped beam and 130% in main beam and the LED are brighter than the dipped and close to the main.
 
Great way to encourage future offers of help... :thumbsdown:

I do not know of anyone who has fitted LED headlights, would assume you must need spades.
 
coding out may work since they are headlights and you would notice if one had stopped working as soon as you went to use them but i wouldn't replace anything else by method of coding them out for that reason as it's usually hard to tell if a bulb is working or not from inside the car. that is why you have the error flash up to help you.

I like LED's and great for in the home due to savings. Sounds like more hassle than it's worth. May be worth checking a general BMW forum rather than Z4 specific as I doubt many have bothered to do this at all to a 13 year old car.
 
Agree with you re coding out rear lights ir indicators, actually lots of people upgrade their Z's to LED or HID but they use third party headlight units just like I have, but I would like to use them in the OEM headlights, and unfortunately BMW seem to change the adaptor type between different models so the E46 is totally different to the Z4

No, you are wrong, it is not possible to "code out" the voltage check, and even if it was, it would be the "current check" that needed removing. The only option is to fool the system into thinking that the correct current is being drawn.

And, how can one give more output than the other, when they are the same bulbs in both dipped and main. The other thing to consider is, yes you may get more lumens from these LED's BUT the retrofit ones will probably have little, if any pattern control, so not only will you probably see less of the road, but you'll be dazzling every other road user.

Nice attitude for a first post, and one that asks for advice/help though :fuelfire:

sorrt if you feel that way but, You can code out the voltage/current check with Carly for BMW and you CAN run LED headlights with no resistor or can bus fooling device, how am I so sure about this, that's easy because I have done it !!! and as far as the Philips halogens go you will have to ask them how they achieve the higher output in their bulb, I expect they know the answer, as far as the aftermarket projectors, they are designed for HID so the optics are very well able to control the cut off and beam pattern without dazzling other drivers, it's not like fitting a HID into a reflector, and As for attitude, well, I asked a simple and polite question, the first post was not an answer but a why would you want to do that retort with no relevance, just dismissive comments so there was the attitude, but like I said I don't hold a grudge and I'm happy to have been able to give you some technical info re LED and Carly coding that you didn't know about,

Strange that, I use Carly regularly, and mine doesn't have the option to disable "bulb out" warnings.. Must have missed it.. You may be able to get aftermarket projectors designed for HID, but they won't be optimised for LED..

Just look under the light module section and you will see a selection for each individual light it's called voltage check, maybe you just weren't interested in that function before :)

The LED's I have have four facets and closely mimic the output of an HID bulb, so no problem with the optics in fact the beam pattern and cut off is superb and very controllable
