Safety note: Warning-light placement rules vary by state and for commercial vehicles. Check local law.
Verdict
The device to carry if compliance matters — commercial drivers, RV owners, or anyone who wants the triangles FMCSA actually calls for. Light-duty commuters may prefer a lighter LED disc, and nobody should expect a warranty.

Frequently asked questions
What does FMVSS 125 actually require?
Federal standard 571.125 sets the size, orange fluorescent and red reflective materials, open center, and stability of non-powered warning triangles carried in vehicles. CARTMAN states this set complies; the triangles themselves should carry the DOT marking.
How far apart should I place them?
For commercial vehicles FMCSA rules put one triangle 10 ft behind the vehicle, one at 100 ft and one at 200 ft on the traffic side; on a two-lane road the third goes 100 ft ahead. Passenger cars aren't federally required to carry them, but the same spacing is a good habit.
Do they work in daylight?
Yes — the fluorescent orange plate is for daytime and the red reflective border is for headlights at night. They do not light up on their own; pair them with an LED disc if you break down on an unlit road.
