This is a pretty simple idea. Has the glint from a reflective object ever caught your eye? Almost all traffic signs have a metallic base and are printed on a reflective vinyl sign stock. They should naturally catch your attention. But they don't. To enhance their visibility, many governments place expensive flashing LED lights surrounding the signs. Here's a better way.

Instead of mounting signs rigidly to a pole, mount them to a pair of spring steel brackets that allow a few degrees of movement in the wind or as traffic moves past. The slight "wiggle" will catch reflections of the sun and/or headlights and enhance the reflectivity and noticeability of any sign using the brackets.

Besides the hardness of spring steel, the brackets would be insanely simple to manufacture. Let your street signs wobble in the wind to enhance the intrinsic flashing capability built into existing reflective road signs.

a flickering effect probably showing the reflectiveness of the aluminum base material [CRXPilot, Oct 30 2024]

Welcome to the 'bakery, [CRXPilot];

This is an excellent idea, and I suggest adding to it a pair of extra- reflective hungry-looking eyes with vertical slit pupils; safer roads through primal fear.

Good idea; however...
Road signs generally use a retro-reflective surface, which preferentially reflects light back to the source (or near enough, since your headlights aren't ON your eyes...) regardless of the incident angle. So wiggling it won't actually changed the reflection.
A full rotation, however, will be very noticeable, like those shiny spinning mandala artworks.

If the reflective stickers were lenticular they would flash just fine.
