Are Car Headlight Brighteners Useful?

[LeReed]

Car headlight brighteners are useful, capable of improving the lighting of older vehicles by up to 30%. Here are some details about headlight brighteners: 1. A headlight brightener is not a machine but a power cable that changes the original wiring from the generator to the headlights, connecting them directly to the battery. This ensures the stability of the headlight brightness. The headlight brightener consists of two relays. 2. The headlight brightener uses the original car's headlight switch assembly to control the relay coil windings of the brightener, thereby managing the opening and closing of the relay contacts.

I've also considered installing a headlight brightener before, since I always feel the lights aren't bright enough when driving at night. These devices mainly work by increasing voltage to make bulbs brighter, but the headache is that bulb lifespan gets shorter. Older cars need extra caution with wiring aging - suddenly increasing current might cause wires to smoke or even catch fire. Actually, just upgrading to better halogen bulbs can significantly improve brightness at a reasonable price. If the budget allows, going straight for LED or xenon headlight kits would be more reliable, as factory-matched wiring is much safer.
