The cargo area of my 2017 ford edge is very dim, there's a small led off to the side but it's pretty dim and very easily blocked. I'm thinking about adding some lights to help the situation, but this is the first car I've owned built in this millennium.
In previous vehicles I would have just tapped additional lights into the existing circuitry for incandescent bulbs and it was fine; new lights would trigger at the same time as the old lights. In previous vehicles however, there was a significantly smaller number of computers and they didn't ever tell me things like "Cargo area lamp burned out". I'm not certain that I can do that in the new vehicle or if I need to look into alternative power solutions. Are there any reasons I couldn't just tap the power and ground wire to the cargo-LED and wire another light source in parallel?
