Cygolite Dash 450 adds four traditional LEDs but they would be more useful if visible from the side (click to enlarge).

The Lowdown: Cygolite Dash 450
The Cygolite Dash 450 is an interesting concept with a main LED light and 4 helper LEDs to assist or to be used as a 'to be seen' mode light. It is a similar concept to the old NiteRider Moab light which used an HID light but incorporated three LED lights to give the light more usability.
Construction is good and the beam pattern is good as well with a fairly flat and wide beam. The main LED lens has cutouts to give it some side visibility. The four helper LEDs though don't do much and end up making the light bigger and having more light modes to scroll through.
