How to Use a Ballast:
Step 1 - Open the hood of your car.
Step 2 - Put on latex gloves. Oil from your fingers can damage the bulb and reduce its lifespan.
Step 3 - Connect the bulb to the ballast by plugging the ballast plug into the bulb socket.
Step 4 - Use two wires to connect the ballast to the car battery. Ballasts made for cars usually come with a plug that encloses the positive and negative wires together.
Attach one end of the first wire to the positive terminal on the battery and connect the other end to the positive terminal inside the ballast plug.
Step 5 - Attach the second wire from the negative terminal on your car battery to the negative terminal inside the ballast plug.
If the bulb and ballast are working correctly, the bulb will light up. Conversely, the ballast may be malfunctioning.
