N2  - The potential result of controlling source intensity to provide optimum contrast under any ambient lighting condition is the basic concern of the paper. Another method for increasing visibility is improving the uniformity of light distribution of the signal indication. The purpose of the paper is to discuss the two methods for improving visibility.<p />
