After sneaking at a copy of "2006 New Car Features IS350/250" at the dealership, here is the info for the LEDs which I think a lot of us would be interested..

Combination Lens - Taillight & stop light LEDx2 0.4/0.4 W
Combination Lens - Taillight LEDx16 1.3W
Combination Lens - Turn Signal Light Wedge base bulb (non-LED) 21W
Combination Lens - Rear Side Maker Light LEDx4 0.3W
Combination Lens - Back-up Light Wedge Base Bulb (non-LED) 16W
Licence Plate Light LEDx1 0.85W

This is a copy which details all the technical specs and how-it-works of differenet aspects of the car (like VDIM, engine/tranmission etc)that the technican has and I ask them to let me take a quick peek.

Hope it will clear the confusion.

 

Excellent. This confirms the specs sheet provided by Lexus in the press release. I think this issue is pretty much settled now. Thanks to everyone for a lively discussion on this issue.

 

Is there such a thing as LED-bulbs? I'm still unclear of the difference say between LEDs in the IS and why the LEDs look so much different in say the Honda Accords...

 

Google is your friend...

Thx, but do ours use LED-BULBS?

 

i think its pretty obvious that they are LED's, the color contrasts RED more than filament. when i first saw the car and the salesman pulled up, I said, "hey cool it got LED tails"

 

BMW 5 series.. 3 amber markers for the front parking lights.. pretty cool.

 

Why does it matter if they use led's or not??
is someone trying to replace them??

 

LEDs light up quicker giving that extra few milliseconds over a regular bulb and also use less power than conventional bulbs.
