ATTACHMT: Attached to letter dated 4-26-93 from John Womack to T. Kouchi (A41; Std. 108)

TEXT: Thank you for your answer to our questions regarding the above subject by your letter of December 30, 1992.

In your answer, there is your view that any device that contains more than three lighted sections, or LEDs, need only comply with the requirements prescribed for three lighted sections.

According to your view, we consider that the lamps having three lighted sections described in the attached drawing No. 1 & No. 2 need only comply with the photometric requirements prescribed for three lighted sections.

So, we would like to have your opinion if our idea is appropriate.

Your kind answer will be highly appreciated.

Attached to Drawings No. 1 and No. 2 of LEDs. (Drawings omitted.)
