发明名称 A retroreflective traffic sign
摘要 A traffic sign comprises a hollow body (20) having a retro-reflective face (30). The body comprises a bottleneck (60) configured and adapted to form an opening into the body. The traffic sign further comprises a lighting kit (50) with a light source (52). The lighting kit and the body are configured and arranged such that the light source, when activated, trans-illuminates the hollow body. The lighting kit of the traffic sign is retrofittable and trans-illuminates a hollow body of the traffic sign. This helps in maximizing the visibility of existing traffic signs for road users. The illuminable traffic sign is useable with and/or without illumination. Further the traffic sign provides improved illuminated temporary traffic signs and relatively inexpensive lighting kits for illuminating traffic signs.
