I have bought LED daytime running lamps for my 2013 Optima and they are sweet.

Question.....still trying to confirm for my mechanics sake this issue. They come with three wires. It appears...
Red goes to Iginition fuse
Green to headlights (Dims LED's when headlight are on)
Ground to Ground
Does this make sense? No other hardwear or relays needed?
