Recently got and old car roadworthy and it has HID headlights in it. =20
The bulbs have an interesting behaviour in that when first turned on,=20
they emit a quick flash of light, then instantly dim, and slowly=20
brighten back up to operating brightness.  What's not good is that every=20
so often, that initial flash causes enough of a power surge to knock out=20
the ECU (=20

.. =20
Or perhaps it's knocking out the aftermarket ignition system (=20
http://www.jegs.com/i/MSD/121/62152/10002/-1 ), as after the surge, the=20
ECU shows "RPM error".  I'm planning on adding some type of filter to=20
the ECU or ignition module power lines (no prob with that), but=20
wondering why I shouldn't try to reduce the surge instead.

How would I go about doing this?  The HID lights have the bulbs, a relay=20
module and a couple ballasts.  Would there be a simple way to reduce the=20
surge for bulbs like this?  Or would doing so impede the bulbs operation?

Cheers,
