Here are two different versions of the outdoor cone lamp from Instructables: On the left is a lantern-style with an internal light source; on the right is a “Christmas tree cone” with string lights poking through. We recommend adapting these by using inexpensive flow-molded cones and battery-powered LED string lights instead of plug-ins. Place cones at the edge of your driveway of wherever there’s a tripping hazard.

4. Neon curb/hazard markers
This is a much simpler, though temporary, version of the illuminated marker — adapted from the glow-in the dark bowling concept. Put sand or pebbles in empty water bottles to weigh them down, then add a glow stick and fill it up with water. The bottle’s amplified glow can be used to mark the curb’s edge, outdoor stair cases, and other risk-prone spots.
This is a clever way to create an original neon sign with inexpensive glow sticks. Studies suggest that traffic signs with unusual messages work best so make up your own traffic slogan. Click for instructions.
