Al go into your lbs and get some of those lights that just strap on, ive got 4 red lights and two white lights.
They don't need brackets. Think there called knog lights. Something like that.
Oh and a tip
Take your front fork out and write in marker pen in the steerer tube , this bike is stolen and your telephone number. If your bike ever gets stolen you may just may some day get that phone call. Takes ten minutes to do it.
Get those lights
