Right side Left side

So I need to replace a turn signal stock and guzzi make Right and left. I don't understand why you cant just flip  it over but oh well.  So looking at the bike the throttle is the right and clutch is left, Right ?

Right!

If you switch sides weep/drainhole will not be on the bottom of the T/S lens.

Right.

Just remember "ALF" (Aft Looking Forward). When you are behind the bike looking forward, your left and the bike's left are the same. It works on boats, planes, cars, bikes and women.
