Smile your on Camera vests

You also don't want to be giving the impression that creating dayglow tabbards or stick on patches with customised printed information on them e.g a personal ID or number plate for cyclists is something that you are willing to tolerate.

I have no issues with wearing hi-viz for the environment type clothing, but tabbards and ID marks are a touchy subject right now.

You need to be careful what you display on clothing in an attempt to improve your safety.

One Researcher (Walker I think) found that cyclists wearing a "POLITE" vest designed to look like a "POLICE" garment actually got less road space from motorists, probably because they did not like being deceived.

A journalist writing in the Guardian a few years ago said when he used one of these it seemed to work OK, until someone threw a milk bottle at him as he was riding through a council estate.

Drivers don't see cameras. I used to have a cheap amazon camera on my rack but it made no difference. They just don't see them. They seem to spot the pass pixi though

I used this website - https://www.hivis.co.uk/hi-visibility.html

You can put whatever text and images you want on a hi-vis vest.

Quality was very good, although check the sizing carefully as it's much bigger than you might expect.

Personally, I found that wearing it made very little difference to the number of close passes I was getting and I stopped wearing it when the evenings got brighter.

If love to get that on a rucksack cover, you know, like the Hump covers

how about something like https://passpixi.com/ ?

I've just spotted this one https://equisafety.com/products/air-waistcoat-bright-yellow-smile-you-ar...

But you could image search for "Smile You're On Camera", then if you find a design you like. Contact one of those "we print your design" sites, and have one printed up.
i.e. a sew/velcro on patch.
