What can LED fog lights be used for?

A:

Quick Answer

LED fog lights can be used for both everyday and off-road driving. These lights can be advantageous because they use 75 percent less energy than traditional halogen lights, so they have a much longer life span.

Full Answer

Light Emitting Diodes, or LEDs, are light bulbs that don't have a filament that burns out. Incandescent bulbs and halogen bulbs are both filament-based; both of these bulbs involve metal wires transmitting an electrical current to a filament to make the filament glow. Both incandescent and halogen bulbs use a mixture of gases to intensify the light they produce, but the difference between the two is that incandescent bulbs use an argon/nitrogen mixture while halogen bulbs use a halogen gas (such as bromine). The halogen gas has the added benefit of helping regenerate the filament so it glows longer, but, for both the incandescent and halogen bulbs, eventually the filament burns out and the owner has to replace the bulb.

In contrast, the LED bulb doesn't use a filament, which means the life span of an LED bulb can be up to five times longer than the incandescent or halogen bulbs, resulting in thousands more hours of use. Additionally, LED bulbs are plastic, making them more durable than their glass counterparts. The longer life span and greater durability are major advantages of LED bulbs, but these advantages also mean LED bulbs often cost more than the filament-based options.
