I know relationship b/w wattage, ampage and voltage. I meant that current is the only issue here, wattage is fine. That type of problem usually occur over long period of time, weaker system might fail after few months (as mentioned with Mazda), since X5 is well built machine it might take few years to fail. But the bottom line is that people should know repair will cost big $$$ and spending $40 for relays+wires is always cheaper alternative. In addition dealer undoubtedly will void the warranty soon after detecting such setup.

There has been only one or two MZ3s with a problem.

OK it sounds we have decided it is better to play safe but if you dont it is just as fine so far.

What about the cutoff ? is the glare that bad?

What are the kits people use? DDM, Apexcone, Phillips based(600$ ), Prolumen etc
