Display-based cycling navigation can be tricky, because you need to take your eyes off the road to see where you should be headed. But with Hammerhead Navigation that issue is no more, due to its completely screen-less, LED-based design. It’s a front light-sized compact device equipped with bright LEDs that indicate the rider with certain information, and it actually doubles as a front light if required. Varying layouts and flashing of the LED lighting provide you with a turn-by-turn navigation, including not just turns, but also hazards, warnings, U-turns, and much more. Just learn its LED-based language, hop on your bike and enjoy a safer GPS-guided ride. $85
