Why don't my LEDs shine ?

If your new LED lamps do not light up after installation, there are several possible causes. Here you can find a step-by-step troubleshooting guide.

1️⃣ LED polarity is wrong – just turn it around!

LEDs have a positive and negative poles, while conventional light bulbs work in both directions.

✅ Solution:

  • Remove the LED from the socket and rotate it 180°.
  • Reinsert it and test whether it lights up now.

📌 Tip: This is the most common cause of non-functioning LEDs!

2️⃣ Check socket or contacts

If the LED still doesn't work after turning it over, the socket or contact could be the problem.

✅ Solution:

  • Check if the metal contacts in the socket are clean and not bent.
  • If necessary, clean the contacts with a cloth or some contact spray.

📌 Tip: Test the LED with another power source (e.g. battery) to make sure it is not defective.

3️⃣ Check fuse – possible short circuit?

If several LEDs or other lights in your vehicle suddenly stop working, a fuse blown be.

✅ Solution:

  • Look in backup plan your vehicle for the fuse for the lighting in question.
  • If the fuse is defective, replace it with a equivalent security out of.

📌 A notice: If the new fuse blows again immediately, there may be another electrical problem.

4️⃣ Can-Bus system – error message or flickering?

Modern vehicles often have a CAN bus systemthat monitors power consumption. LEDs consume less power than traditional light bulbs, which leads to Error message in the on-board computer or flickering can lead to.

✅ Solution:

  • Use special Can-Bus compatible LEDsdesigned for such vehicles.
  • Alternatively, you can resistance (load resistance 5W-10W) parallel to the LED to solve the problem.

📌 Tip: If you are unsure whether your vehicle needs Can-Bus, please feel free to contact us!

5️⃣ LED defective? – Test function on external power source

If none of the above solutions work, the LED may actually be defective.
