Sunlite's HL-L175/TL-L330 LED Combo is an easy way to be seen and stay safe when riding after dark. The powerful headlight uses an advanced 1-watt LED for brightness beyond its size. Plus, it boasts steady and flash modes, a 35-hour run time on the included AAA batteries, and it attaches to any bar via an easy quick-release mount. Out back, the taillight runs for up to 100 hours and casts a bright light with its 1/2-watt LED. And just like the headlight, it has steady and flashing modes.
