This is from a members bike:

Are the holes for the turn signal stems the only difference from the OE tail light without the holes?
If so, do they hold up over time or do they crack from vibration with the stems attached?
I am considering adding the holes to mine and moving the turn signals back but I am concerned about the durability.
I might just add one of these instead:

But again the added weight of the bracket and then the turn signals may not be such a good idea.
Any thoughts on this?
