Would you consider a high viz vest over a regular jacket?
High viz fades, gets dingy and becomes low viz long before riding gear wears out. This way, any of your jackets or riding suits becomes high viz simply by putting the vest on over, and you can restore the high viz as easily as replacing the vest.
You didn't like the yellow of that jacket you ordered. With a vest you can choose high viz yellow, orange or fuschia. Whatever high viz shade you want.
Speaking of visability, I think silver is one of the least eye catching colors for a helmet. I like white (for being visible without being obnoxious), but I'd certainly consider high viz if it were an option in lids that meet my needs--it's not. My current lid is naked carbon fiber, but has a little high viz reflective 3M Diamond Grade tape (amazing stuff for day/night conspicuity)
Best conspicuity thing I've done I think is amber photon blasters. Not blinding by any means, but they have a subtle eye-catching flicker.https://www.skenelights.com/online-store/Photon-Blaster-p80153941
A commuter I sold a bike to saw them on my other bike and bought a set for himself.
