| Subject: | Re: XeVision HIDs |
Interesting info from a subject expert.
Thanks,
Stan Sutterfield
PS - the 2000 TT was stock HID.
If your car came with HID stock and you have not changed your bulbs to
Chinese
bulbs, there is no way your car has 6000 or 6500K bulbs.
All cars come from the factory with 4200K bulbs. Your headlight projector
may be
making it look bluer.
The highest DOT legal bulb color is 5000 to 5400K. These bulbs do not come
in new
cars but are for replacement only to match an older aged bulb color that
has
color shifted. Philips offers a 5000K, GE a 5100K and Osram a 5400K. Those
are
the highest color bulbs legal in the USA for autos. All cars in the USA
come
with 4200K bulbs.
The only TRUE 50 or 75 watt bulbs currently being made are about 4000K.
We have tested many of the Asian made (including Korea) bulbs, some TRY to
handle
50 bulb watts but none do it very well. As for 70 or 75 watt, Only the
Germans
have a track record or results with that bulb power level.

Only the E/P-mag (afaik) continues to provide a tach signal with the
ignition switch turned off. A Slick or Bendix mag will stop producing
pulses when the ignition is turned off (unless a vent plug pick-up is
installed). I suspect you haven't wasted your money.

Subject: AeroElectric-List: Magneto tacho signal
I have a magneto serving my bottom plugs and LightSpeed EI serving my
top
plugs.
Because I wanted to be able to read engine speed at run-up with either
the
magneto or EI turned off I installed a transducer that screws into the
accessory pad (where the mechanical tach sender would normally attach).
This
gives me a tachometer signal at all times to send to the glass Engine
Management system.
But now some-one is telling me that the magneto continues to provide a
tacho
signal even when it is switched off. Is that true. Have I wasted my time
and
money installing a tachometer transducer.
cheers Bob Barrow

According to my research your cars has D2S bulbs. Most likely Philips but also
possibly Osram brand. If those are the original bulbs you should consider to replace
them. They are 9 years old and likely producing only ~70% of the original
lumens. That is unless you drive very little at night. after 2000 hours of
use you should consider to replace the bulbs. You will notice a difference but
your old ones will be at ~5000 K while new bulbs at 4200K.

LED still has a long way to go to compete with HID as a landing light. This is
true in terms of total lumens and reach (distance).
