Defective fischertechnik lamps can be easily replaced by LED.
In order for the LED lamp fits into the fischertechnik building block, we use a 12 volt LED with integrated resistor.

Step 1: Remove Old Lamp

Remove the old lamp.

Step 2: Inserting the LED

Put in the 12 Volt LED. Bending the legs.

Step 3: Ready

Test the function.

If you want you can also use a 12 volt flashing LED.

You can use 5mm or 3mm LED.
The 5mm looks best.
