How to make the manufacturing certificate?
You must enter all the required data in a form that you will find in the following link, once the lamps have been purchased. https://asxstore.com/pages/homologated-led-bulbs
Here's a more detailed explanation of how to do it:
Steps for the manufacturing certificate
To be able to drive and pass the MOT, your bulbs must have the mandatory documentation certifying that they are approved.
The certificate is individualized with your vehicle's data.
The data that we will require in the form are:
-Make, model and registration of the vehicle .
- Vehicle approval password : you can find it on your Technical Inspection Card, either in section “K” or in the text that appears at the bottom left, after “… with the vehicle approval password number: …” Enter all the characters, including slashes and asterisks. (Ex: e12*2007/36*2714*93)
-Bulb type and model: Ex : ULtraled H4
-Product serial number : Or batch number. It is printed on the neck of the bulb, it is a four-digit number separated by a slash. (Ex: 07/23)
- Headlight approval number : This is printed on the headlight itself, on the lens, or on the inside. It consists of an “E” followed by a number, contained in a circle. Next to it there must be one or two numbers, generally four digits each.
Once you have completed the form, please check that all the information is correct. It is your responsibility to enter correct and real data and not to falsify a document that must be examined by official bodies.
For any issues with your certificate, you can contact our Customer Service phone number 658 747 558 and we will try to resolve it as soon as possible.
If you need the digital signature for your certificate:
When you receive the email with the certificate, reply to it requesting the signature and include the purchase invoice.
IMPORTANT: When passing the ITV, it is very important to bring the certificate along with the ticket or purchase invoice properly stapled.
It is advisable to bring it in PDF format.
How to request the digital signature of my manufacturing certificate?
When you receive the email with the certificate, it is essential that you reply directly to that same email requesting the digital signature. Make sure to attach the corresponding purchase invoice, as it is a mandatory requirement for processing the certificate signature.
Additionally, we remind you that to pass the ITV, it is very important to present the signed certificate along with the purchase ticket or invoice. Both documents must be properly stapled, as this facilitates verification and meets the legal requirements for this process.
If you ever need assistance with your processing at an ITV center, feel free to contact us at +34 658 747 558, and we will provide the necessary advice.
What type of light bulbs does my car use?
It is important to check your vehicle's owner's manual . You can also consult a vehicle professional or an authorized service center.
* For example, if your car has H7 halogen, then H7 Led will fit.

How to install LED bulbs?
Installing the bulbs is quite easy. First, you anchor the base of the bulb to the headlight and then you insert the bulb and orient it so that it produces the right beam of light.

*There may be some headlights that need an adapter to mount the H7 model to the headlight.
Does my car need an adapter to install LED bulbs in the headlight?
The only bulb models that need an adapter are the H7. For the others, the adapter is the same as the halogen bulb that the car has as standard.
Check this list to see if your car needs it:
*There might be some vehicle models that require an adapter and/or decoder for LED bulbs.. If so, it is recommended that a professional check your car's headlight to see which of the models we have on our website fits it, making an observation and comparing it with the images of our models.
There are models where, due to the trim level or because different headlight manufacturers exist, multiple adapter models may fit. To check if your vehicle needs an adapter, review these two options:
- If the H7 bulbs are secured directly to the headlight with metal clips (no adapter is needed).
- If, on the other hand, the bulb’s own connector acts as the mounting or fastening mechanism for the headlight, then you most likely need an adapter.
Adapters are only required for H7 LED bulbs; other types do not need them.
Will my vehicle need a CANbus decoder?
The necessary use of the CANbus decoder is not linked to specific vehicle models but rather depends on the vehicle's equipment.
The more control units it has, the higher the likelihood of needing one. Its use is optional in case the burned-out light message appears on the onboard computer.
What is CANbus fault?
This occurs when the warning light "blows out" appears on the dashboard. The car may then stop sending power and the light will flicker or turn off.
This is because the car detects that there is lower consumption, and can interpret this as a blown light bulb.
It is solved with a decoder, which is a resistor so that together with the bulb there is more energy consumption and it is equal to the halogen ones.
It happens rarely, but it can happen.
What is the difference between Super and Ultra Led?
The ULTRA is more powerful than the SUPER and already comes with the heat sink fan and prevents CANbus failure by 90%.
· Ultra: 23 watts of power and 1725 Lumens
· Super: 13 watts of power and 1170 lumens
Will I pass the MOT?
Regarding documentation, of course. In some centres they may ask you for a digital signature to “officialise” the document, which we will insert without any problem upon request at Customer Service.
Another issue is the lighting test. Before your inspection, you should always check that the bulbs are perfectly compatible and that they emit an appropriate beam of light without glare.
If you have any problems, you can contact us at +34 658 747 558 or by writing to the following email: comunicacion@asxstore.com
Do Super White halogens produce blue light?
Although the bulb is blue, the light is 6000k white, cool white.
What is the lifespan of a halogen lamp?
Halogen bulbs have a lifespan of up to 3,000 hours. Our bulbs have a longer lifespan because they are quartz, UV protected and anti-vibration, both the original yellow and super white bulbs.
What is the technology behind the ASX LED headlights?
ASX LEDs use the 3570 CSP chip, a more modern chip that can deliver more lumens/watt than a standard CSP chip.
What warranty does the product have?
All ASX products have a 2-year warranty, ISO, INMETRO and E-MARK quality certification, and if the products under warranty are not repaired, they are exchanged for a new one.
