To ensure safety among the cyclists, some regulations related with cycling are in force by Swedish authorities including the obligation of bicyclist to use the light for bicycle during the night. However, in the implementation there are still a lot of cyclists who do not use lights when cycling at night or even if they use the lights, only the front lights are used. This is, of course dangerous to the safety of the cyclists because other road users especially motorized-vehicle drivers are not aware of their existence. Bicycle traffic counts, behaviour studies and interviews with the cyclists are conducted. The bicycle counts were carried out for 15 minutes period started from 21.00. For the behaviour studies, it was conducted every 15 minutes periods for 2 hours from 21.00 until 23.00. The interviews with the cyclists took place in five different locations, the locations that are the same as for behaviour observations. The final conclusion is that the economical factor is not the factor that determined the use of bicycle lights. It is also found that cyclists have already known their obligations to use the lights. From the interview result, it is shown that most cyclists believe that the function of the light is as an existence marker (to be seen) not to see the way during darkness.
