CANBUS LED Bulbs: How to Make Your Own & Avoid Computer Errors - Share Your Knowledge!

Hello, I am aware of the physical identification of CANBUS bulbs. I want to make a few LED bulbs, but I want to avoid computer errors.

If anyone knows, has any materials - please answer ;)

greetings.

As for my factory fix, it's a BASKET! He can get around it, but what and how is it, not this forum.
I am opposed to any lighting modifications !! The fact that LED lighting is modern, mounting this type of light to older models is pointless, and it looks FABULOUS ... and the effect on the road worthy of a smile ...

An example from yesterday. Dude put in parallel under the hood in his E 46 5W bulbs and in led lamps !! What was the name when I opened it and talked about the infusion of something else and I looked at the engine ... Avoided fact, mistakes, but what purpose ??? Please!

Added after 1 [minutes]:

PS Lighting, direct power supply does not fly on CAN, but its control. As already ...

Any new bulbs-CANBUS ??? Where do such interesting terms go, on smartheads?

CAN bulbs are crap invented by sellers on Allegro.
Just like "full graze" - because, for example, Mercedes cannot have ASR and ASD at the same time.
But what traders will not do to confirm the buyer what a sensational and unique product he buys ...
All this CAN in bulbs is based on the fact that a classic bulb (e.g. from a blinker) takes almost 2 amps, and the LED one much less, and it is recognized as a lighting fault. So you need to insert an additional resistor inside, which will make the lighting checking controller not sense the difference. Simply put: the power consumption has to be the same and this is the whole great CAN bulb (which has nothing to do with the real CAN)
Actually, there is so much on the forum that I am surprised that today I have such a "day of goodness" ...

Hello
I have such leds (can-bus) in Leon and resistors alone are not enough.
In addition, there is an npn transistor which, when starting the car, gets an impulse and starts to conduct.
I tried to put together such a system on diodes with resistors and it crashes every time an error and cuts off the voltage on this bulb.
The bulbs are controlled by the bordnetz module.
Pulse filling can be adjusted between 75-100%

Hello, thank you for the answers.
However, I do not understand why so many emotions ... A man enters the forum to find out something, and he gets a "day of goodness". "Grace without" - because it misses the point ;)

zwrek1 - I expected such an answer. Thank you and best regards.

Djleeon, no nerves, no such bulbs and period. Lighting control in modern cars is a comparison of the resistance and power consumption of the light source, any deviation of these parameters from the standard is treated as a lighting fault. In order for the LED to work without firing the bulls, it is necessary to ensure that the source used exhibits identical working parameters with the original. Not all cars with CAN network have lighting control, lighting control is not reserved only for cars with CAN network

It's best to think - after all, you put ordinary light bulbs into these lamps and everything works, there are no "CANBUS" bulbs. Combinations with a resistor do not always work, because with the right resistance, its power would have to be comparable to the power of the replaced bulb, and secondly, some cars also check the turned off bulbs with short current pulses, and the resistance of the bulb's cold fiber is much lower than that resulting from the power and rated voltage .

ABOUT! A new era of CANBUS bulbs is coming, after the era of stepper motors.
I have already had a few cases in newer cars when the function of the damaged bulb is taken over by another one, the cars came from other workshops because they could not cope, e.g. the direction in front is constantly shining.
KEEP IT UP. There are CANBUS bulbs, and you have to replace them because you can burn your computer.
I just rub my hands against such stupidity.

Hello and welcome!

I would like an honest opinion about Can Bus LED bulbs. The mechanic once installed such bulbs for my Audi a6 (3.0 TDI, year of production: 2007):


After about 6 - 7 months, the left bulb died, there was also an error on the board.

My question - will installing filter bulbs, which are proposed by sellers, extend the life of these bulbs? The first time the mechanic did not use this filter, he tried to reprogram the readings so that the computer would not perceive too low resistance of the LEDs as an error.


Thanks in advance for your advice. Regards!

"CAN Bus bulbs" is an invention of traders to catch deer and naive people.

99% of the products available on the market are Chinese indulgence. The LEDs that make up the lamp are of very low quality (usually the so-called "out-of-catalog") and they work with too much current (so that they shine nicely, strongly). So don't expect this crap to last long. Enchanting and combinations with "filters" won't help. Buy yourself another one and hope that they will be at least a bit better quality.

I see that this forum went to PSY amateurs speak on a topic in which they have no idea. To ignorant pseudo experts, the IC-Driving rail for LED lighting with Can-Bus modules does not resistors and do not write stupid. And thus lowering the question-answer level. So much for the topic.

Who above is an amateur?

because it is a Polish forum elektroda.pl and with real help it has little in common and is only a field of performance for the chosen ones. if you know English, people will be happy to help each other on the first industry forum. And here, yes, at PW and for money! POLICE!

Will you find idiocy like this topic there?

In the car forum alone, you could count hundreds of people who have something to show off, professional knowledge based on education. And a few hundreds who licked the subject of the press sections usually titled "Do you know ..."

Perhaps, gentlemen, I am a hundred years behind Negroes but:
Can is just a bus between drivers and not bulbs.
The bulb checks can be turned off depending on the car.
In my opinion, giving resistors (heaters) to show in the area what a Cossack is = nonsense.

It is puzzling that some of them, having been here for almost ten years and having over 300 posts, write about help and Polishness, having in their achievements have a nozzle in "the option helped". Prove yourself and you will be appreciated.

I'll put in my 3 pennies and 2 points.
Suppose I have this case:
I want to change the trunk and interior lighting to stronger LED lights, but necessarily in the original installation and places.
The car has light bulb controls, cold and hot.
Both can be turned off with a computer. Ironically, the checking turns off but only on the computer.
The message appears randomly on the clocks.
The light bulb is blinking. On the ignition, a short pulse every 10 seconds, with the door open, it lights up but goes out for 1-2 seconds every 20 seconds, where when it goes out, an error on the clocks is triggered.
The difference with bulb checking enabled is that when it will crash a bug burnt - cuts it off.
I tried to work around it with a capacitor and a resistor measured under a cold light bulb, unfortunately the resistor did not last 2 minutes, and the 1000uf capacitor only slowed down the flashing effect, the error continued.

I admit that I did not invest in a super "CANBUS bulb" for testing, just because I gave up and gave a little more powerful bulbs, but I am curious theoretically how they did without large resistors

Moderated By serwisantscani1:

In what technical dictionary did the colleague find such vocabulary ???

The solution with a resistor and a capacitor (connected in series with each other and in parallel with the bulb power supply) is intended to simulate the resistance of the cold bulb filament (impulse tested), however, it will not work in circuits with adjustable brightness or with a smooth ignition / blanking based on PWM - the resistor becomes they slept. Why the resistor connected in parallel to the "LED bulb" with a resistance matched to the cold filament of the bulb burns, it does not need any explanation.

serwisantscani1 Clinging on.

tzok Okay, while in the main interior lighting it makes sense, in the additional lighting (reading satellites, mirror lighting) and the trunk, where the light bulbs work on the on / off principle, there is no longer, and LED bulbs are sold that people buy and no problem they darken as normal, so there is something in these "CANBUS" that makes it possible. [mod = "serwisantscani1"] No clinging ....

Statute.

It depends on the car and the solution used to control the brightness and control the bulbs. Sometimes a 1u-10uF capacitor and possibly a 4k7-10k resistor are enough.
