      <title>SUPER HIGH BRIGHTNESS FIPS UNDER DIRECT BATTERY DRIVE</title>
      <link>https://trid.trb.org/View/172733</link>
      <description><![CDATA[This paper describes the brightness improvement of fluorescent indicator panels (FIP) for automotive application.  The brightness improvement factors are analyzed and the possibility of getting high brightness under direct car battery drive is discussed.  With this approach, a newly developed car clock FIP is described.  Its brightness is 1100 ft.  L at 12 V operation while the old FIP had a brightness of 400 ft.  L.]]></description>
