Do you have rear handlebars? Or a volt meter?

Volt meters (multimeters) are cheap and essential for what you are contemplating. Maybe someone will chime in with a real answer for you, but you could probably run to Walmart, pick up a volt meter, and find out for yourself more quickly, with the added bonus that you'd then have a voltmeter. But, Aventons come with 48 volt batteries? How/why would they provide a 12 v lead? It's possible with more electronics that would consume valuable amps, but again, why would they do that? A lot of bike lights run on a range of voltages, like 8 to 69 volts. (I don't know exactly, but something like that.) Your lights are almost certainly running on 48 volts; You can very easily check with a volt meter.
Also, I generally look for accessories with button batteries or that are USB rechargeable. I want to save my bike battery for getting me home from a long ride.

The Aventon Aventure headlight is made by Spanninga. It is model HL32 and operates at 6 volts DC. The rear light is also Spanninga and is a Pimento-Guard. On the Aventure, it operates at 5 VDC as a tail light and 6 VDC as brake light. Both seem to be OEM-only products.

This is the route I went on my Aventure, though I've got two separate mini 4x 18650 packs in there. When one runs dry I connect the second one up, and take the dead one in to charge, using the other 'till it's dry. It would be nice to tap into the ride battery, but in practice I find it more convenient to have things like my headlight be separate from it so when/if I accidentally run the drive pack flat (happened to me once already) I still have light.
I also really like that by having headlight power separate, I'm not stuck with a dim hard to view display when my light is on.
I do wish the Aventure had USB power out built-in.

A must have for troubleshooting or collecting data to get assistance.

There should be a constant 48v going to your display, from the controller. That is the source that I tapped in to. I connected a dc-dc 48v->12v converter to run my light assembly. I also used the same source to add a wireless charging phone cradle.

Would you mind sharing the converter you used to do this? and pics of it all would be great too!

I used this one.
There are many kinds. Buck converters are smaller, but dont seem very water resistant.
Here is the light assembly.
