The development of a high tech image analog cluster providing good readability is required by today's customer. To satisfy this trend, we have developed a highly unique analog cluster, which features very sharp white lit pointers with evenly illuminated white dials on a black acrylic face. These features are primarily achieved through two new lighting sources: 1. Pointers made from thin, lightweight Cold Cathode Discharge Tubes. This pointer creates very high brightness, regardless of temperature, by enclosing xenon gas in the tube, and was designed into a single side electrode structure. 2. Circular shape Cold Cathode Tube Installed Behind Each Dial Applique. This application creates very bright high quality illumination. In this session, we would like to introduce the construction and system of two new lighting sources for lexus, LS400. This technology provide improved readability.

Besides automobile instrument clusters requiring the high precision and legibility, they must also appeal to the user's fashionable sense. We have been proud of introducing such the cluster, named New Electronic Analogue Meter for the LEXUS LS 400 high quality luxury sedan. This paper describes design features of it as the followings; (1) The acrylic lens with black out effect. (2) Utilizing the cold cathode discharge tubes for pointer and back light of dial applique. (3) The virtual image warning indicators producted on the dial applique of the speedometer or tachometer.
