A secondary alert light for a motor vehicle is composed of a light holder, a light convergence ring and light emission devices. Wherein, positioning posts protruding from a reflection cover on the light holder secures the light convergence ring which is light permeable having on one side provided with fluorescent material to collect the light, provided with posts to match those on the reflection cover and at least two grooves on its peripheral at equal spacing to house light emission devices for the light convergence ring collecting light emitted from the light emission devices by means of the light convergence material to create a significant light ring for improving alert effect.
