Early warning devices (EWD) are reflective triangles placed behind a stopped or broken-down vehicle to warn approaching drivers. This collection has the Autosport reflectorized EWD and the Megatools EWD in yellow or red.
How to use an EWD
- Placement: set it on the road well behind your vehicle, in the same lane, and farther back on fast roads.
- Visibility: keep the reflective surfaces clean so headlights pick them up.
- Storage: keep it folded in the trunk where you can reach it quickly.
Related
Wear a reflective vest at the roadside. See also safety cones and booster cables.
All products from KHM Megatools are genuine.
