I was surprised to find that the light in the trunk of our 2024 Hyundai Ioniq 5 was not an LED light, which means it will use up a lot of the small 12V battery when in use.
I bought a 6 pack of DE3175 LED ($7) lights from Amazon and the steps below show how I installed one in our car.
Here is the old yellowing incandescent light.
What I bought:
I used a small blade to lift the front edge of the light cover.
The assembly slides out easily.
I used a small screwdriver to release the clips holding the power supply cable:
The assembly was then free and obviously no longer powered.
I uncliped the cover from the assembly with the screwdriver:
I popped out the old light and inserted a new LED one in its place.
Since the polarity matters, and the polarity of my LED light was not marked, I tested that the polarity was fine before reattaching the cover.
Then clipped the cover back on and inserted the power cable all the way.:
The last step was to simply push the assembly back into place.
