Is this perhaps the guy that followed Ewan and Thingy the long way down ? :084: :015: :164:

Sounds like the hardcore version of the Dentist in Little Shop of Horrors.   :008:

Breaking news: I restored my yellow LEDs back on and the annoying error shows up again (seemingly randomly).

As there can't be any proper earthing on a motorcycle (in normal use ;-), could I safely assume that a Faraday cage (obviously shielding the fuseblock and/or the internal components of the projectors, not the keyless receiver ;-) should be grounded to a conductive part of the frame?

Ferrite RFI damping beads on the power leads to the LED lights?

Or a DC filter of some kind as there is also the possibility that the noise\interference is been radiated from the supply cables to the LED lights, this would require a filter as close as possible to the first electronic parts of the LED lights.

I know that some filters exists (capacitors, dampeners...), but I didn't know about "ferrite RFI damping beads".
Have to check for that, thanks!

OK, found this article: https://www.analog.com/en/analog-dialogue/articles/ferrite-beads-demystified.html#

Way beyond my knowledge in electronics, but still gives food for thought!

1 - EMI conducted through the wires up to the fuseblock seem the most probable culprit. I doubt that airborne EMI would be powerful enough to disturb the keyless receiver that is more than 1 meter away from the LEDs (energy decreases according to the inverse square-law with the distance). This conjecture is supported by my experience on the PT Cruiser (which FM radio is parasited by tiny LED position lights). Problem is that EMI will certainly contaminate the whole electrical system of the bike, making it actually a resonating EMI amplifier. So I have to cut EMI as soon as possible (that is between the fuseblock and the lights; ideally right onto the projectors, but doesn't seem that practical).

2 - I don't want to keep any EM signal coming from the lights, so I can go for a pretty broad filtering device.

3 - On the other hand, I'd really like to filter EM noise specifically in the keyless system frequency range.

Oh well, I have to think it over...
