Push hard. Mine takes quite a bit of force to activate the tail-light.

If it works with full pressure, then you should look to adjusting the activation switch (refer to your User's Manual).

Pretty standard to have hard-to-activate rear brake light.

You shouldn't have to push hard. With mine I can depress rear brake lever with pinkie finger and it activates light no problem. There is also a distinctive click u can hear. I would have dealer chk and adjust it. Or like Macca suggests the easy adjustment.
