If your imported vehicle is older than 20 years, the DOT road safety equipment is exempt from compliance. Your JDM lights are legal. Oddly, they made that requirement 5 years shorter than the EPA's emissions exemption.
The scematic on the page you linked is exactly what I had in mind. It would be cheap to build. It would be even cheaper if you nipped over to the pull-it-yo'self yard and filled your pockets with high-quality underhood electric relays found in Japanese and German cars (because Nippon Denso and Bosch beats USDM lowest bidder). Those are severe duty relays that can live outside forever. Or you can buy a 12/24v relay board on amazon for $5, it will be fine as long as you install it in the vehicle's interior.
Calling it a "logic circuit" as they are on that ih8mud page is overshooting the hoop by quite a bit. It's a bang-the-rocks-together simple relay isolation circuit. I suppose one could call it a Turing engine, since it reacts to voltage on one circuit and controls another, without affecting the original data message, but that's also a stretch.
