PIAA designed the LED itself to project light backwards into a segmented, multi-surface reflector which defines the beam pattern. The LP530 was designed from the ground up to be an LED light, so this isn't just an LED bulb thrown in a halogen housing. The downside is LEDs need reflectors specifically designed to maximize the light spread. LEDs are far more efficient than a traditional incandescent light, like halogen lights which waste a large amount of energy in heat. As energy moves through the LED, the electrons jumping from gap to gap releases energy in the form of photons, or light. LED, Light Emitting Diodes, are a different technology than traditional halogen light bulbs. The wiring harness does not include a fuse, which is recommended for installation. If fog lights are optional on your vehicle, you should be able to wire in the factory switch for a more integrated look. The kit includes the wiring harness and switch needed for installation. Like all fog lights, they need to be mounted low for best results.

They are designed to fit in grilles or under bumpers. The FF75 has a wide, flat, and low spread of light ideal for lighting up the road and not bouncing light off the fog, snow, or rain back at the driver.Įach FF75 is roughly 2.5-inches tall, including the mounting bracket, and 6-inches wide. Once computers were powerful enough, Hella began calculating the three dimensional shapes necessary to use all the light coming from the bulb and getting it exactly where it needs to be on the road.

For most of the history of the automobile, light reflectors were symmetric paraboloids which were then cut-off by lenses or shades. That mirror is notable however as it is what is called a free-form reflector. The FF75 isn't a cluster of LEDs, it isn't one big projector, it is a classic halogen bulb with a mirror reflector behind a glass lens. With such a long history of quality lighting products, you might expect that Hella's fog lights would avoid current fads and just provide great lighting, which is exactly what these FF75 lights do. European manufacturers have relied on Hella for decades to provide lighting solutions for some of the best cars in the world. Hella has been making automotive lighting for so long, the company's first lamps were powered by candles or kerosene – I'm not joking.
