Maybe because they bought lights that might have resistors but still dont pull enough current.
I tested the amount of resistance required and posted my findings in a forum but I forget which one I posted it in!
The end result though was that you cannot get away without still drawing something pretty heavy... and need a low resistance like 10 Ohms, 15 Ohms or something like that.
I tried lots of values between 10 and 400 Ohms.. hoping to have as little current drain (and more importantly, heat) as possible.
The best way around this is to go to Jaycar and buy some 10 Ohm ceramic resistors and install them in the boot lining in parrallel with the wiring for the lights in question.
You can use heat transfer compound and cable tie them to the metal of the boot lid, this way there is very happy cooling going on for the resistors.
Since you're talking about reverse lights heat isn't so much of an issue, because they are only on for a short time, but with the number plate lights, you need to consider they are on for hours at a time and the platic housing could melt with some chinese made error-free LED lights because they do get HOT!
I did take a photo of my install in my B7, but I can't find it now.
