Reflective PETG filaments?
I'm looking for PETG filament that has the same kind of reflective properties as what you see on safety vests, bicycle reflectors, street signs, etc. Does such a thing exist?
Thanks!

You can get this sort of thing:
No idea if it is any good but it is a good place to start. There are other colours as well

That's more of a fluorescent filament, it seems, as it requires blue or UV light to hit it to make it fluoresce. I am looking more for something that works like a bike reflector, as I want to print a new address plate or numbers for my mailbox so that it would be visible at night (my street has no lighting) to emergency vehicles, or just passing traffic.
RE:
If you want reflective then no you will not be able to print it. Bike reflectors work by having a mirrored and shaped surface under a coloured transparent cover. Light comes in, bounces around and is then returned (roughly) to source. Have a look at one up close and you will normally see the prism shaped indents in the reflective surface under the clear red. The ultra bright stripes on high viz work similarly but using clear spherical reflectors.
Florescent should work like a high viz jacket and should glow when hit by a cars head lamps, particularly modern vehicles with halogen, HID or LED lights

I would just buy something like this:
