It's only really useful if it's significantly separated from the cyclist's eyes (IE on the bars not on the helmet) and a regular old light does pretty well for that.
Depending on the pattern of your headlight, I can imagine this light working much better than a regular light as far a distinguishing problems in the road. It would be interesting to test if it ever came to market (and wasn't ridiculously priced).
