Nowadays, many more new types of automobile lights appeared. Plenty of drivers do not satisfy with the original lights on their vehicles, thus they prefer to make some modification. People mainly choose to modify HID or LED to replace their original lights, but still some would like to modify Angel Eyes or Devil Eyes. There is no doubt that modifying HID or LED is for lighting and being discriminating in driving for safety consideration. Then why people feel like modifying Angel Eyes and Devil Eyes and what on earth are they?
Currently, there are two kinds of Angel Eyes while concerning the emitting materials: CCFL and LED. CCFL is commonly known as a cold cathode tube and most LED monitors are using this material now. Its emitting principle is adding high-pressure into pipe poles, which makes the mercury electron of the inner tube impacted with gas atom to produce ultraviolet light that hits the phosphor on the tube and converts into visible light. LED Angel Eyes is emitting diode, which actually is constituted of several LED particles arranging into a ring. Compared with CCFL, the internal drive voltage of LED Angel Eyes is much lower than CCFL, therefore, the LED Angel Eyes do not need ballast to start as CCFL do. Moreover, LED Angel Eyes have advantages of easy installation, better energy dissipation and safety than that of CCFL. However, as LED Angel Eyes are point sources of light, the lighting aperture is not continuous, which makes it less aesthetic than CCFL. In addition, after a long time of using, the electrodes of the CCFL light tube ends easily become dark, especially modified by some unqualified products, which is quite serious.
In fact, Angel Eyes are installed as headlights mounted outside the aperture. They were first used in BMW, mainly as daytime running lights and side lights. Devil Eyes are similar to Angel Eyes, yet it is one point different. Devil Eyes are embedded within the light, while Angel Eyes are outside. The premise of installing Devil Eyes need to add lens or lens coming with the original vehicles. Light that adding to the lens reflects from the spherical lens, just like a ball. Angel Eyes are a lot easier to assemble and disassemble, reducing the chances of lax seal due to assembly and disassembly. Besides, Angel eyes are equipped outside the light, which would not block the light, while Devil Eyes would due to installing inside.
From my point of view, though I write a lot about the Angel Eyes and the Devil Eyes, I think it is no use installing Angel Eyes or Devil Eyes. Except aesthetics, I cannot think of any other advantages about them. For a car, lighting is really a serious problem. No one can ignore it. For driving safety, I suggest you to install LED driving lights or LED light bar, which becomes a trend for vehicles. At present, some newly-produced vehicles are equipped with LED daytime running light, which means LED becomes more and more popular in vehicles production. Do not hesitate, buy a LED driving light or light bar for your beloved vehicles, and let them guarantee your driving safety.
