This special Kit is just for those who require extra bright lighting when driving in extreme conditions. Phantom X is using pure 50w ballast system and special 50w bulbs to accommodate the extra power that the ballast is producing. 50w will give almost double the brightness of conventional 35w HID System. We recommend the usage of this kit to properly tune their beam, so it does not disturb other road users. Proper care must be taken while using this HID kit.
