You will also need a 5 amp car fuse. Auto zone has them for about 1$.
Use the hood release bolt as a ground point for the lights.
If you run the wires correctly it looks 100% OEM I set the LED color to match the red trim on my car and it looks so good!
Zip ties help and a coat hanger to run the wires through tough spots.
