The invention relates to a tubular lamp, particularly relates to a high-intensity parapet lamp for road or bridge, which can display various colors and is controlled by computer program. The cavity of the lamp is sealed with soldered illuminants and light-reflecting circuit board; the power supply wires pass through the inner tube and the ends of the power supply wires are connected to multi-contact connector assemblies. The lamp is lit up at night and is controlled by computer program to produce a flowing effect which can indicate the direction.
