Introduction


Headlights are placed in front of the vehicle to light the road ahead. A research conducted shows that most of the road accidents that occur at night are related to low light conditions. This means that a higher percentage of vehicle related accidents occur mostly in the dark, at dawn or dusk. Hence night-time visibility is important to highway safety. There are lights and lamps on a vehicle which helps the driver to clearly see the road, pedestrians and other vehicles at night. Lights are also used by drivers to signal other vehicles especially when overtaking or diverting a road to avoid accidents. For these reasons there are certain requirements on where the lights should be located, how many they are supposed to be and how bright these lights should be.


Interestingly the first cars did not have headlights. The headlights became common in cars in the 1920s.


Modern cars use a wide variety of lighting systems. Economical cars have traditionally used halogen bulbs due to their low cost and rugged reliable nature. Currently halogen headlights are still the common headlamps being used but this is eventually going to become antiqued in favour of new technologies such as HID, LED and as futuristic as it sounds LASER. High intensity discharge (HID) bulbs are very expensive and the high definition LEDs are also very expensive and it’s one of the reasons why they are found in luxury vehicles such as the Mercedes Benz E400. Headlights are different from one car to another.


Use our Oedro LED headlights guide to help you know how headlights are tested and dangers associated with wrong use of headlight for you to avoid them when using your car or vehicle and you will be well on your way to a vastly improved working environment.



How headlights are tested


Before the vehicle leaves the factory a series of tests are done. Engineers drive test vehicles during the day time to check a lot of things from how it drives to the comfort of the driver. Engineers have to wait till dark so as to test how their headlights will perform. Different companies use different approaches to test the performance of their headlights.


In order to evaluate the headlights, sensors are placed at a distance to measure the amount of light as the car drives towards them. These sensors are placed strategically so that it can measure both the low and high beams from different approaches whether it is straightway or curve.


Headlight system are evaluated not only on how well they illuminate the road but also on the glare for an oncoming driver. Not all headlights perform the same. They vary greatly even on a single car model. This is because of the bulb technology used as well as how the lights are aimed at the factory. However more weight is put on the low beams performance since they are used more often than high.



Dangers associated with the wrong use of headlight


Your car should live up to the standard of the road. Headlights don’t make any noises and the car doesn’t start behaving oddly when problems arise. However this does not mean that they are not without difficulties which will affect the performance of the vehicle.


Drivers use the headlights to blind others while driving. Anyone who has driven at night knows how annoying some drivers are when using headlights since they use headlights to blind the other drivers because they fail to lower their high beams and this impacts vision and could cause accidents. Many drivers have an habit of always turning their headlights on to increase visibility and this blurs the vision of other drivers and could cause accidents.


Today’s headlights can turn yellow and foggy without the knowledge of the driver. When the headlights turn yellow or become fogged they pose danger to other cars and pedestrians.


Dim automotive headlights pose dangers and safety hazards when driving in a winter storm or on a thunderstorm late at night. Dimming or burned headlight bulbs means that you can’t see the road or other drivers can’t see you while driving. Research shows that if one headlight bulb is gone or is fading or dimming the others are not far behind and they will start dimming or fading too. So it is advisable to replace the two bulbs the same time. According to headlights expert about 2500 pedestrians are killed at night every year crossing the road in many cases because the driver can’t see them because their headlights don’t shine brightly enough.


Wrong use of hazard lights may cause accidents while on the road. Hazard lights are used to warn other drivers that there is danger on the road ahead. Most drivers think that they can stop anywhere so long as they put the hazard lights on. Hazard lights should be used be used to warn other traffic that your car has broken down or you are in a dangerous place that will affect other traffic.


Headlight flashing which is the act of either briefly switching on the headlights of a car or the act of momentarily switching between headlight’s high beams and low beam in an effort to communicate with other drivers. The signal can be intended to convey a variety of messages including a form of warning to other drivers of road hazards or it can be a form of aggressive driving. The legality of headlight flashing varies by jurisdiction. Headlight flashing can be a form of aggressive driving which is meant to intimidate others into speeding or otherwise driving unsafe. For instance if a driver keeps his or her current speed and flashes headlights when another driver is trying to overtake, they intend to communicate ‘Stay back, I’m not slowing down’.



Conclusion


No matter if you are driving down a dark street or up a foggy mountain pass, equip your vehicle with sufficient visibility from Oedro LED Headlights. Replacing your old headlight with a newer and brighter headlight from Oedro to improve night-time visibility. Oedro has everything you need when it’s time to replace your dim headlights.


Good headlights shouldn’t cause excessive glare. Properly aimed low beam headlights from Oedro LED Headlights light up the road ahead without temporarily blinding drivers of incoming vehicles.
