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. ________________________________ Message 2 _____________________________________ Time: 12:30:19 PM PST US From: "Peter Pengilly" Subject: RE: AeroElectric-List: Magneto tacho signal 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.

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 _____ Find out how here Use Messenger in your Hotmail inbox ________________________________ Message 3 _____________________________________ Time: 01:36:45 PM PST US Subject: AeroElectric-List: Re: XeVision HIDs From: "XeVision" 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. Dan -------- 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).
