    Basically all the world apart from North America uses the UNECE regulations I was referencing including Japan. So EU and Japanese Prius lights are the same, I believe.

    Maybe the side signals on your 2010 were a brighter US spec.

    Or maybe they're faulty, or some sort of wiring problem. If you're not being hyperbolic with 'can barely tell it's lighting up at all,' maybe check the voltage at the connectors.

    I'm not saying this is the reason, but I wired my lights exactly like the wiring diagram, which means I effectively tapped into the violet and pink wires before they went into the PDBA and became the yellow and blue wires. The biggest reason I stuck to the wiring diagram was my OCD/desire to make future service easier, but I also wasn't absolutely certain if the PDBA did anything to the signal. After all, Toyota could have easily run the wires back to the rear light straight from the junction connector, but they chose to run them to the PDBA for some reason.

    It's remotely possible there are some resistors in the PDBA that are reducing the strength of the signal for some reason. You're already working with K21 for the folding mirrors, maybe try switching to the violet and pink wires to see if that makes a difference.

    The US Prius gen 3 and 5 don't come with side blinkers, so there isn't a US equivalent regarding brightness for them.

    After cleaning up the wiring by putting it through the proper connectors the blinkers look brighter during the day. May have been poor connections when they were barely twisted together.

    Just need to troubleshoot my left BSM signal then everything will be back to normal except the power folding which I'll finish later. Might have to run a new wire if there's a break in the positive wire, but hopefully it's just a small section I have to rewire.
