The present official stop sign for use at night - a red light or a red light in combination with an illuminated white vat-type sign - are not sufficiently for road users. A new stop sign has accordingly been developed, which in daylight looks the same as the existing one - a white disc with red edge- but differs from it when used at night in that it incorporates a red light and as small blue ""point light"" which flash alternately.
