The worlds most powerful battery-integrated light for cyclists who require exceptional range of vision. Seca Comp has distinguished itself as an unrivaled cross-over light, with a perfect combination of high-power in a compact, battery integrated design. By utilizing two battery cells, Seca Comp is one of the few cycling lights on the market able to achieve powerful output without quickly fading. Custom-engineered optics do not waste light and is specifically engineered to provide cyclists a wide beam ideal for handlebar illumination. All Seca lights have ETS (Enhanced Trail Sight): 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.
