I went for the 3x180 ohm resistors in parallel on this one, and initial tests on the moped showed that they worked perfectly!
Thanks to all for contributing with great help!

The moped in question is not my own, it belongs to my sister's son (I'm sure there's an english term for this kind of relative). I'm already a 'big boy' (a.k.a adult) :-D.
The owner told me the light broke when the voltage regulator broke down on the moped, causing overvoltage in the...
Thanks for the input again!
As can be seen in the photos I attached, there are no heatsinks or large copper cooling areas for the leds and the circuit board is packed inside a waterproof (not anymore :-D ) plastic housing, so there's not much cooling provided here.
I think I'll try that two...
Thanks for all quick responses and useful remarks on the subject!
The white leds are quite small, 3 mm I think. The red ones are larger square shape leds with four legs. I'll attach a couple of photos of the whole assembly to clarify further.
I agree with you that the design may be poor using...
Hello to all from a noob!
I'm trying to fix a broken moped tail light (led based). A power spike burned a resistor so bad, it's impossible to read the colour codes on it.
Now I would really appreciate some help in calculating the needed resistance value so I can replace the resistor. I've...
