Even if the battery is dead light come on when i hook up cables?

If the battery in your car is completely dead, it may be difficult or impossible to start your vehicle using jumper cables. This is because a dead battery cannot provide any electrical power to the starter motor or other electrical components in your car.

However, if you are able to connect the jumper cables correctly and securely, you may be able to get a small amount of power from the donor vehicle's battery to light up the lights in your car. This is because the lights require a relatively small amount of power to operate, and the donor vehicle's battery may still have enough power to provide this.

However, it is important to note that this is only a temporary solution, and you will not be able to start your car or drive it with a dead battery. You will need to either replace the dead battery with a new one or charge it using a battery charger before you can be sure of starting your car.
