F25 LED Bulb Error Fix.

Problem, I have not been able to find much about replacing the OEM incandescent turn and brake bulbs with LED’s. Like many I was disappointed that my new X3 did not come with LED’s for the turn signals and brake lights (My two year older F10 does have them) so I started pulling together as much info from all the forums I could find and then started filling in the holes. I have read good and bad about Error Free LED Bulbs and did not wish to cut any wires to add load resistors, so I looked into coding as an alternative (I just started coding on both my FXX vehicles with great success).

Result, I am 99% sure I have figured out the codes which check for front & rear turn signals, brake lights, fog lights and reverse light errors on my F25. I tried it this afternoon by removing a bulb then coding that particular bulb to “not active” and it worked, the BC warning and fast flash rate both went away immediately. Now I am going to order regular LED bulbs and see if there are any problems. If this works I will post the codes for others to use.

I didnt try this but there should be a way to turn the bulb sensors off as you dont need them for LED lamps.

Yes, that is what I did, basically deactivated the Warm and Cold check for bulbs. Wish there was a way to print out or save the screen shot from E-Sys as it would make trouble shooting and posting results much easier.

There are tools to capture screen shots like Snipping tool etc. but the readily available though not so convenient tool is "Print Screen" and then paste it on a Paint for editing before you save it as jpg file.

That's cool that you're doing it through coding. I did "error free" leds in the front of my F25. If anyone is interested, I can try to track down the model number and stuff. I do have a video that I took during install to compare the incandescent to the led, so I can try to find that as well. Here's a pic:

OK, here are the ones I used in the front.
http://www.ebay.com/itm/TWO-AMBER-No...36b227&vxp=mtr

Eventually that link above will die, so for future reference:
Item title: TWO AMBER No Resistor Required 7507 BAU15s PY21W 20-SMD LED Lights
eBay seller: maple125

PS - there's another LED thread here that I posted this same info to: http://www.bimmerfest.com/forums/sho...d.php?t=650495

Thanks for the info. I have been successful in using non-error free bulbs and coding out the errors. I purchased my bulbs from Superbrightleds.com (7506) 48 SMD bulbs. I will be using them in the front and rear (front requires me to grind off one of the pins but it works great). The 48 SMD bulbs I got are significantly brighter than the stock incandescent bulbs. I have more details on X3 Bimmers site using the same original title.

@SpaceManGray, can you please let me know if the leds you purchased for the front are brighter than the bulbs that came with your car? I'm sure that they will work just fine on dark/night environment, but how about on sunny day conditions?

Any Input is much appreciated

Here's a photo of the difference. The turn signal bulb on the left (passenger) side is the stock bulb, the one on the right (driver) side is the LED that I linked to above. I believe the stock bulb is slightly brighter, but I probably wouldn't have noticed without the direct comparison.

Thanks!! I do see a little difference on the stock bulb, but hardly noticeable.. What I'm really concerned about is at full Daylight, could you please share your thoughts on that?

I think they look fine, but I'd like to show you a photo so you can decide for yourself. I don't have any photos of them in the day and it's not the brightest day today but I'll see if I can get one today out on the street and it might be good enough.

Wow! Thanks for that...

How about this 127 SMD LEDs?

Interesting, looks like they blink really fast, is that accurate or just the video?

Additionally, I just looked at the Youtube version of the video and it is not as good as the one on my IPad, the Youtube video rate maybe making it look "fast flash".

I purchased 4 of the same 7506 Red LED bulbs (two for rear turn signals/two for brake lights). I also just purchased two 7506 Amber LED's for the Front Turn Signals.

YouTube videos are 30 frames per second, iOS shoots video at 24 fps... so that might explain why the flash rate looks different after YouTube has converted your iOS video.

No, they are not "fast flashing" I believe you the difference you are seeing is between the LED sharp on/off and the incandescent bulbs fade on/off. They flash at the same rate as the stock LED's on my F10.

Cool. And for the brake lights, do you use another set of the same red bulbs or are they different?

Spaceman they look great.

Just ordered 6 bulbs. I tried ambers for the rear turn signals - we'll see how those work out.

Cool.

Not sure what you ordered exactly, but in case you missed it further up the thread, the front and rear bulbs are not the same model. The fronts have offset pins on the socket, so they're 5707 (PY21W). The rears don't have offset pins, so they're 5706 (P21W). I have no idea why BMW did this since they seem to be the same bulbs other than the socket (and color of course). samillerfl mentioned he used 5706s all the way around but used a grinder on the PY bulbs to remove the offset pin. Anyway, just wanted to mention that in case you weren't aware of that and wanted to change your order.

I am interested in the ambers in the rear. I think all signal lights should be amber, but I never thought much about doing this in the rear of the X3 because I thought there was a red lens over the turn signal bulb anyway.

Post pics and/or video when you get them going.

I definitely will. I read about the pins, I thought they had to be modified all around not just some, so I was just planning on grinding them off either way. Shouldn't be too difficult and from what I heard the 5706 was brighter.

I've had a few vehicles with amber bulbs behind red lenses and they look cool, when they're off everything is red but when they light up they're still amber, it's a neat effect. I'll post photos when it's done.

Just for clarification...BMW X3 F25 has stock amber incandescent bulbs inside a clear lens for the front turn/marker lights (Part #7507, these bulbs are Single pole/filament with 150 deg offset retaining pins). The stock rear turn bulbs and brake bulbs are clear incandescent inside a red lens (Part #7506, these bulbs are single pole/filament with 180 deg offset retaining pins). Why BMW did this I do not understand, it probably had something to do with bulb manufacturer agreements. Bottom line is the bulbs are the same except for the retaining pin positions and color. I personnally went with Super Bright because they have been in existance for some time, most of the reviews have been positive and my previous purchases have been positive, (the bulbs may have been a little more, but I just bought a $50K vehicle so a couple of $ more for a bulb that will last the life of the vehicle is worth it). When doing my research on replacement bulbs, I discovered that there are more options (i.e number of leds and shape) when purchasing 7506 (often referred to as 1156) bulbs vs. 7507 bulbs, and that by removing one pin from a 7506 bulb it will work in the 7507 socket (it does and fits well not loose at all). Research "What color bulb shoud I buy?" as bulbs of the same color as the lens are more intense and brilliant than other colors. I believe most all US states require front signals to be Amber/Yellow and Rear signals to be Amber or Red with Brake lights to be Red. The for the Amber or Red for the rear turn signals is that some vehicle manufactorers use dual filament turn/brake lights which would have to be Red.

When filing down the pin from the 7506 bulb, does it matter which one you remove?

No, you can file either one.
