Featured in the photo above is the Bontrager Ion 700 headlight (just $89.99 and super-bright!) and Bontrager Flare R on the rear ($59.99). The Bontrager Flare R is a game-changer for daytime visibility, something few tail lights have yet paid attention to. All USB rechargeable! You can tell from the photo just how awesome a setup this is; you can literally descend at speeds similar to daytime if you wish, but please be aware that deer can run into the road at any time, so caution is advised.
This is an awesome combination. The Bontrager Ion 700 provides massive firepower, despite its small size and light weight. The Bontrager Flare R in the rear is simply incredible, with a light that stands apart for its surroundings, day or night, better than any we've seen before. Well worth the $59.99; it's built to last and protect.
For not that much money, you can ride more safely in the daytime and take back the night. Rid anytime you need, or want to. Just be very careful about deer when it's dark, and be aware that the most-dangerous time to ride is twilight (when the sun is setting or rising), due to low contrast. Bascially, you blend in with the surroundings.
