Rear lights on your bicycle essentially serve a single purpose. They make you more visible in low light conditions, whether that be at day or at night and help to reduce the chance you will be involved in an accident with another road user.

Most rear cycle lights mount on the seat pillar but there are also some that mount on the bicycle frame. You need to ensure though that wherever you mount your cycle light that is conforms to local legislation as there are, in most countries, minimum height from the ground requirements as well as other requirements. For example it may be illegal to use flashing strobe type lights although they now seem to be more and more widely accepted.

The old filament bulb type of cycle lamp looks to have had day now with more and more LED style lights coming onto the market with comparable power and usually more favorable battery life.

As mentioned above there may be some limitations as to the type of light you can use on your bicycle and one of the most common restrictions is that the light must be 'steady' as opposed to flashing. You will find that most modern LED lights have a steady mode as well as a flashing mode but you may find it beneficial to have two lights mounted. One steady to meet the legislation and one flashing to make you more visible. Some rear lights come with multiple banks of LEDs that allow you to have some showing steady and some flashing.

One word of caution is that although a flashing light tends to be more visible to motorists and other road users it is sometimes difficult to judge the distance to them and there is a suggestion that if the driver behind you is drunk they could actually be recalled to the flashing light. These caution notes though only really serve to backup the fact that you should have both steady and flashing lights on the rear of your bike.

Another reason to have two lights mounted on the rear of your bicycle rather than relying on a single unit is battery life. You tend to find that LED lights will simply fail much quicker once battery power falls below a certain level. So, it is useful to have a second light installed that you can switch to in the case of failure.

So if you are in the habit of riding your bicycle at night, make sure you are safe by fitting adequate lighting to the rear (and front) of your bike, and remember that whatever solution you go for when lighting up your bike it needs to conform to local legislation.
