Are Car Headlight Brighteners Useful?

Car headlight brighteners are useful as they can improve the lighting of older vehicles by up to 30%. However, the increased bulb wattage also means higher power consumption. With the rise in current, the wiring may generate heat, leading to increased resistance. The messy wiring after modification is prone to wear and grounding, which may result in burnt wires in mild cases or even vehicle self-ignition in severe cases. Additionally, this will undoubtedly affect the lifespan of the car bulbs. A headlight brightener does not actually brighten the lights but is essentially a power cable that changes the original headlight wiring from the generator to a direct connection to the battery, ensuring the stability of the headlight brightness. The brightener is composed of two relays.
