What is a ballast?
In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw. Within a second the lamp would overheat and burn out. During lamp starting, the ballast must briefly supply high voltage to establish an arc between the two lamp electrodes. Once the arc is established, the ballast quickly reduces the voltage and regulates the electric current to produce a steady light output. (extract)
100% waterproof and 100% dustproof.
Resistance to heat and aging.
Best performance guaranteed for the lowest price without sacrificing the product quality.
As long as 35W power supply, greatly reducing vehicle power system load, the power loss can save up to 50%.
Low voltage protection: the ballast will turn off automatically when the voltage is lower than DC 9V, when the voltage is back to normal it could work well.
High voltage protection: the ballast will turn off automatically when the voltage is higher than DC 16 or 19V, when the voltage is back to normal it could work well.
Non-load protection: the ballast will turn off automatically when bulb is not connected or connected incorrectly, it would work well after the bulb is connected well.
Short circuit protection: the ballast will turn off automatically when there is a short circuit, it would work well after it is connected well.
Reverse protection: the ballast will turn off automatically when the electrode of the input was reversedly connected, it would work well after the it is connected well.

Xenon bulb is a light source and a replacement. So the effect can’t be compared with the original. The modified effect of each car is different that depends on the battery, Line, Lamp holder, etc.
