Did you know that the world’s first electric headlamp was invented by the electric car company in Connecticut, USA, and it was powered by electric cars in 1898? Since then, there have been significant improvements in the type of lamp and its function.
If you drive at night and you see some blurred yellow headlights approaching the opposite direction of the road, you may find an ancient classic. These headlights use a century-old tungsten wire technology and are rarely used by car manufacturers.
If you see a bright blue/white lighthouse arrive, it may come from a luxury Mercedes or BMW that will pass at full speed. These vehicles are equipped with high-intensity discharge or HID lamps or better known as xenon lamps (xenon brenner) at the factory. Xenon headlights (xenon brenner) are known to be brighter than conventional headlights, given the same voltage/power consumption, so they are more popular.
Clearly, blue/white light provides drivers with better road visibility, and luminaire manufacturers have quickly realized the growing demand for such headlights. Many drivers have converted headlights into xenon bulbs (xenon brenner) that are easy to install. Currently, there are many brands and brands on the market that only need to browse the Internet.
Check the existing lights before deciding to replace them. If your car is equipped with original headlights, the first thing to know is if you use a separate light bulb as the drive beam and the high beam. Still others use a single light bulb for low beam and high beam. A single bulb that can perform the immersion and highlight functions has two filaments inside the bulb. When you turn on the headlights, even if the high beam is turned on, the meter filament will remain lit and continue to illuminate. Headlights using a single double-strand bulb are easily detected when removed because their connection is 3 pins.
On the other hand, a headlamp using a separate road lighting bulb has a single needle connection and its low beam fitting has a double needle connection.
Next, check the original manufacturer’s specifications because the other bulb manufacturers do not meet the previous pin connection specifications. However, you will find that almost 90% of automatic light bulb manufacturers meet the previous plug specifications.
Before the popularity of HID, many cars switched from traditional tungsten bulbs to halogen bulbs. Although the function remains the same, Halogen emits white light and a thinner filament. The advantage of a thinner filament is that it emits a brighter light. However, for the finest filaments, it is easy to burn and in order to overcome this problem, manufacturers have been able to extend their life by adding a halogen gas to the filament.
The constant development of beacon technology has always focused on brighter, more durable bulbs that use the least amount of energy. The brightest light bulb is not always the most useful because it produces glare that temporarily blinds the driver in the opposite direction of the road. The popularity of HID bulbs is due to their brightness and the resulting beautiful blue/white light. It is said to burn 3 times brighter than a halogen bulb and has a life expectancy of 10 times. However, if you plan to invest in such a lighthouse, be sure to spend more on the HID bulb.
The latest headlight technology focuses on LED bulbs or LEDs. The advantage of LEDs over other existing bulbs is their longer life and durability. Its small size gives the headlamp designer more flexibility. It is well known that many of the LEDs produced in the 1970s and 1980s are still in use today. The use of LEDs for tail lights, brake lights and room lighting is quite common, but because of the high cost of production factors that match the color of daylight, the headlights are limited.
