Two little horns, hollowed out, so that they slide onto the E-gear paddles.

Mine fit perfectly i.e. no sticky tape or glue was required to keep them on.

With that the paddles become thicker (which to me feels better), about 2x
as tall (which does not exert too much force on the micro switches even if
I pull them at their top tips), and the blinker/lights/wiper stalks remain fully
usable (since the paddles do not extend downwards).

Perfect!

Thank you MAcarbon!
