Light and Motion Seca Comp 1500 utilizes two battery cells to achieve trail-worthy output without a quickly diminishing fade. Custom-engineered optics do not waste light and is specifically engineered to provide cyclists a wide beam ideal for handlebar illumination. A penetrating LED array gives a powerful spot beam in conjunction with a diffused flood beam ideal for both road and trail use to provide exceptional range of vision for serious rides. Amber sidelights and a daytime pulse mode ensure road visibility but a secondary button allows the side lighting to be turned off when on the trail.
