LED Lighting Systems
LED lighting systems are quickly becoming the most popular form of lighting for cyclists around the world. LEDs are battery operated lights that emit a bright, white light, brighter than any other bulb on the market today. These systems usually come with hi and lo options, making them great for use in busy parts of town after dark. These lights are also long lasting, meaning that for years you will only have to purchase the battery power to run them. There are some disadvantages to owning a LED light however. Because of the brightness, these lights can be distracting to on coming traffic, making the lights illegal in some areas. These lights are also rather large and identifiable, making them prime targets for thieves. Luckily, these lights are easy to remove so you can simply unattach them when you park your bike at night.

Halogen Light Systems
Halogen systems may not be as sophisticated as LED systems, but they are much less expensive. These systems produce a cone of light that, with most models, can be adjusted to suit the cyclist. These systems are very reliable, provided that you keep the battery packs charged and ready for use. Another benefit is that halogen lamps and bulbs are inexpensive and more than one bulb can be attached to a battery pack, allowing for more light. Disadvantages of using a halogen lighting system are pretty standard. The more bulbs you attach to a battery pack, the quicker the battery will run out. You will always have to worry about keeping your batteries charged and operable with this kind of system.

H.I.D. Systems
H.I.D. systems are relatively new to the biking community. While these systems do offer the brightest light available, they are fairly expensive at this point. The bright lights also consume a lot of power, meaning that you will have to change your batteries and possibly the bulbs quite often.

Dynamo Systems
Dynamo systems are popular because they are run through a generator making concerns about charging batteries obsolete. While dynamo systems may seem ideal, there are a few disadvantages. Unless you have installed a special system, once you stop pedaling (that activity runs the generator) your lights will go out, which could be potentially dangerous. Some believe that dynamo systems are dangerous and could blow up if you begin to pedal your bike too quickly. This is a myth, these systems are in no way dangerous.

Xenon Strobes
Xenon strobes are commonly used as a tail light or a mechanism to show motorists that you are passing by. These powerful flashing lights can fit in the palm of your hand but can amazingly be seen up to 2 miles away! These lights come in a variety of sizes and colors, allowing a cyclist to choose the model that best suits their needs.
