The Whole Life Of Headlights We are born to be the eyes of cars and trucks. But unlike human eyes, which have eyelids, we are directly exposed to elements, like sunlight, rain, snow... And we have to confront other things like dust, debris, sand, and the like. So......we need some invisible protection. Check out how Alziria helps headlights stand up to all these. Against The Elements (1) As headlights, the first thing we need to face is sunlights. What's bad about it? - The UV. It may cause the lenses to age and yellow in very short time. So we need UV protection on the lenses. Otherwise we may grow old very soon. No worries - all Alziria Headlights come with an anti-UV coating on the lenses. Also, this anti-UV coating has been hardened to fight against dust, debris, sand, and the like. Against The Elements (2) Another common thing we need to face is rain water. If rain water gets its way in, we will stop working, immediately. Waterproofing depends on how we are sealed and whether we have gone through air-tight tests... Again, no worries - all Alziria headlights are well sealed with premium silica glue and gone through air-tight tests. Light Better How well we light the road does not only depend on how bright we are... But also on the beam pattern, i.e. where the light goes. The lights should go where they should be. All Alziria headlights have been checked for the beam pattern before packaging. It's Alziria's mission to help each driver light the road better, and longer. Why is anti-UV coating so important? Because it determines how long you can have the headlights. Without anti-UV coating, your headlight will go yellow or cracked within 3-4 months. Then you’ll have to buy a new pair again, and thus the extra cost. What’s total reflection reflector and why is it important? As unbelievable as it may sound, most aftermarket headlights don’t have reflectors that really reflect. Alziria is well aware of this and all our headlights use total reflection reflectors for your safety . What’s beam pattern and why is it so important? Beam pattern determines where the beam goes and whether the lights cover all the areas that should be covered. It’s as important as the brightness.
