Has anyone managed to change the license plate light? still waiting for LED swap :(
LED swap to what? It's LED from the factory... (Or so the OM says.)

So I got these bulbs, but the map lights can't be manually turned on without the plastic cover getting a little stuck.

The JDM AStar Bulbs work for me though in that the plastic cover doesn't get stuck when manually turning on the map light.

Does anyone else have issues with the interior LEDs not fully turning off when the lights are off? Like. Dim glow as if there is a power leak? My 2016 ex didn’t have this issue. Put the same bulbs in my 2018 ex-t with sensing and it’s doing it

Solid State Relays, FETs, etc., pass some generally negligible amount of leakage current when off. The engineer designing the system knows this and knows that the load in question, a traditional light bulb filament, will not glow with this little current and/or its resistance will allow the SSR to fully release. You've now put in a much more efficient (higher resistance) load that will glow with that little current. Because of this, a slight glow is maybe not surprising.

Can you think of any explanation for why it hadn’t happened in my 2016 civ, but is now happening in the 2018? And Is there any way to add resistors or something to prevent this glow?

Maybe they changed how they switch the current to something that has a higher leakage current? (To make one of the BCMs a $1 cheaper or 10% more reliable?) Or maybe they've changed other loads on the same circuit? Who knows?

A resistor in parallel with one of the bulbs might help. It'd take some testing to figure out how much current is there/analysis to figure out what value and how much power it would dissipate. YOYO.

update, bought a single canbus LED and put it in one of my dome lights, and it stopped all of the lights from glowing.
