5.1 ‘Sign Good’ Indicators
Each driver board has an indicator which shows as a white spot at each end of the sign. One-way
signs having one driver board will show a spot at one end only. For two-way signs with two driver
boards, the presence of an indication at both ends confirms that both drivers are operating.
