Cygolite Dice HL and Dice TL

The lights feature built-in sensors that detect ambient light levels. When in auto mode, they seamlessly switch between steady beams for night riding and high-visibility flashing patterns for daytime use, so you don't have to manually adjust your settings.

With 150 lumens up front, the headlight is designed primarily for urban commuting and being seen by motorists. While it provides enough illumination for well-lit city streets, you may want a more powerful, dedicated trail light if you frequently ride on completely unlit rural roads.

The set includes flexible, tool-free mounts that wrap securely around most standard handlebar and seat post diameters. Because they are flexible, they are easy to swap between different bikes without needing any extra hardware.

Yes, the Dice combo is built with a water-resistant construction. They are designed to withstand typical road spray and light rain showers, though they should not be submerged in water.

Both the headlight and tail light feature a built-in low battery indicator. This light will alert you when power is getting low, giving you enough time to plug them into a USB port for a recharge before your next ride.

Yes, the system includes light mode memory. When you turn the lights back on, they will automatically return to the last mode you were using, saving you the hassle of cycling through all eight options every time.
