Bike Master Turn Signals

Has anyone installed flush mount turn signals from Bike Master?  I have a pair for the front that came with a sticky pad and a bag of bolts, scews and washers.  But I do not see how I would use the bolts or screws.  there is no place that I can see on the turn signals to put a scew or bolt.  Is it just the sticky pad that holds the turn signals on? doesnt seem like it would hold to me.

Not sure if those are the same as others i have seen but you will have to drill 2 small holes to use the nuts/bolts. If you unscrew the lens you will probably see 2 small holes pre drilled into the alum backing.

O ok thank you I am having a hard time finding a place to put those flush mounts on my F2 so maybe I will just resell them, has anyone put flush mounts on an F2?  O and just FYI  clear alternatives turn signals are bad quality, the glue that holds mine together is coming apart and the turn signal bulb is melting one of them.
