2018 C650GT: insert reflectors in license plate holder 'vacuum hole'

[LanceTokyo]

My 2018 C650GT has the large, raygun / vacuum nozzle looking license plate holder. It looks massive and heavy but is a single injection molded plastic piece much lighter than it looks.

Rather than trash it in favor of a much lighter looking assembly, I wonder if anyone has inserted round reflectors or lights. I haven't measured it yet but it looks like round reflectors would fit easily.

Are you sure it does not house the radar detection for the blind spot indicator?

 

[LanceTokyo]

Good question but pretty sure not. The hole bottom is flat, there are no transducers apparent in it, front or back of the bottom.

I think those sensors are in the mirror stalks. Mine are pretty worthless anyhow, lots of false indications.

The hole is just over 50mm diameter.

That is where the detectors are, hope you didn’t block those holes.

No, I think not. There is no indication of wiring, transducer, anything.
I think the proximity detectors are built into the mirror stalks.
