Brake light spinners

[metall_guitarist]

Has anybody ever seen these things in action? I've tried to find a video of them or something..if they work like i imagine they would..they seem pretty bomb to me, especially in some 3D altezzas..but i want to hear if anyone else has seen them or just input in general about them. If possible i want them in my turn signals so they spin when i'm turning or switching lanes..etc.
