Issue with lens flares

Hi people i need a little help here.. sorry about my english.

Well i have some problem with unity 5, i try to configure the flares to the directional light and doesnt work. After that i add the lens flare component to this object and the lens flare was added in the scene but when i run the game, the flares doesnt show.

So what am i doing wrong.. i dont sure if this is some error or a bug from unity3d 5

By the way the procedure that i am using is described here http://docs.unity3d.com/Manual/class-LensFlare.html

And my system preferences
macbook 13' retina display
os x yosemite
Graphics intel iris 1.5 GB
Processor intel core i5 2.3 GHZ
RAM 8gb

i AM using unity 5

well thats all,any help will be apreciated
