Step1
Evaluate your budget and survey your options. Whether you visit a bike shop or shop online, you'll find bike flashers in a variety of price ranges, depending on brightness, range and mounting design. You don't have to purchase the priciest model, but when it comes to safety, you can't afford to skimp.
Step2
Buy a light with high numbers of light-emitting diodes (LEDs) or super-bright LED design. Most bike flashers have moved from fluorescent to LED technology due to the power of LEDs and their ability to outlast fluorescents when turned on and off frequently. However, bike flashers vary in the number and type of LEDs they are designed with, so make sure you find one with maximum light-producing qualities for the best visibility.
Step3
Buy a bike flasher with 180-degree range. These types of flashers contain LEDs on the front and sides of the light, allowing cars to better see the cyclist.
Step4
Choose amber or red bike flashers, so you don't confuse the drivers with whom you share the road. Since white lights are typically associated with headlights, you don't want the driver behind you to think you're coming toward him. Red and amber lights are generally associated with the back of a vehicle.
Step5
Buy a rechargeable flasher if you plan to use it often. Most bike flashers take AA or AAA batteries, and battery cost may become an issue. Decide whether you're better off spending more upfront, so you can recharge your flasher's batteries.
Step6
Determine what type of flasher mount will work best with your bike. If you'll be changing bikes frequently, consider a flasher that can attach to a backpack, fanny pack or belt. If you're looking for permanence, find a flasher that mounts tightly on your seat post or rack.
