LED Number Plate Lights

Yep, I did.

Ok cool. I'll send them an email too. Will try some experiments tonight with the lights aswell and will post the results.

just got mine in the mail...

Did you guys register on their site for warranty?

Just checked my batch number 11-03 and I have no problems.

Ok - some very interesting results.

The resistor boxes aren't the problem - it's the lights themselves.

These are the tests I just performed.

R-Dash lights in the Golf R, lights turned on. AM reception in the Golf R = bad. AM reception in the Tiguan parked right next to the R = good.

R-Dash lights in the Golf R, lights turned off = AM reception good in Golf R

R-Dash lights in the Golf R, resistor boxes plugged in, LED lights unplugged, lights turned on. AM reception = good.

R-Dash lights in the Golf R, LED lights plugged in, resistor boxes unplugged. AM reception = bad.

Now here's the interesting thing.

If only ONE of the LED lights is plugged in - AM reception = good.

It only seems to be an issue when both LED lights are plugged in.

I also wrapped up each LED light in a ball of aluminium foil, and it made no difference. I suspect that it's some kind of resonance between the two LED lights that's being put into the wire.

So I had a little play around with the R Dash LED lights.

The actual LEDs can be plugged in either way - by that I mean the plug which goes into the LEDs isn't "keyed", and so it can go in both ways. It's only a 2 pin so it's not overly important. But I did the following:
- Disconnect both, AM fine
- Connect left light plug pins "up", AM fine
- Switch left light plug pins "down", AM fine
- Connect right light plug pins "down", AM interfered.
- Switch right light plug pins "up", AM interfered.
- Switch left light plug pins "up", AM interfered.
- Switch right light plug pins "down", AM interfered.
- Unconnect left light, AM fine.

So effectively, it doesn't matter what way the cables are plugged in, nor which side light is plugged in... as soon as you have both lights plugged in, the AM is interferred with.

Ahh - my bad... I didn't see Corey had already done this.

Also my batch is 11-06.

Interesting. The LED bulbs I ordered from eBay (w5w 194 5050 SMD canbus no error LED) had a problem that when I had one LED and one normal bulb in it was fine, but as soon as I put a second one in (no matter which bulb or which side) the MFD would display the "check number plate light". Didn't try the AM radio at the time...maybe I should?

Anyway, gave up on those and ordered some R-Dash ones that seemed to be error free...

Ahh - my bad... I didn't see Corey had already done this.

Yeah I did. But my conclusion isn't that it's not the resistors. I mean, I have no method of determining which one it is. It's possible that the resistors are "in active" until the LEDs are plugged in and the circuit is complete etc.

Not very exposed to international trade are you? I think they're the ones laughing all the way to the bank mate
