Automotive lamps tend to fade out and dim off over time as they have an infinite life span depending on the type of technology used for their manufacture.
Headlights are the main source of light in your vehicle. With the developments of the latest automotive lighting technologies, almost any vehicle can get improved headlights due to the vast selection of aftermarket LED and HID kits that are actively pushing out the Halogen lamps into oblivion.
The halogen automotive bulbs originated from the incandescent lamp by undergoing a few improvements. Traces of halogen gas, often iodine or bromine, return the evaporated tungsten to the filament, raising the temperature of the filament and increasing the light output and the life of the lamp. Halogen lamps are pretty straightforward and easy to install but produce amber light, can suddenly burn out due to the voltage spikes and drops and go into dark mode after no more than 1000 hours of use.
High-intensity discharge (HID) lights, or simply known as Xenon lamps, light up the most of the road including sidewalks. The way ahead of you is clear in any weather conditions as the xenon light is much more intensive than of halogen lamp. As for lifespan, xenon lamps on average serve their duty for 3000 hours which is a few times longer than halogen counterparts. On top of that, xenon light imitates the daylight with the maximum resemblance and the driver's eyes get less tired.
Bi-xenon headlights comprise all the advantages and drawbacks of ordinary xenon lamps but with one very important feature. While you should get individual xenon lamps for high and low beams, Bi-xenon can accommodate both streams in one lamp by changing the direction of the light. So in case, your vehicle's lighting system does not support the separate installation of high and low beams, bi-xenon is a great option for aftermarket lamps. Just make sure you have igniter in place for xenon leadlights.
LED lamps are a recent breakthrough in the automotive headlight industry. Their advantages in terms of light quality, lifespan, and efficiency make LED kits a popular replacement option for car tuners. Being more precise about the advantages, automotive LED lamps consume less energy and thus saving fuel in the tank, can last around 20 000 hours (833 days actually). As for obvious cons, the lighting is poor in snowy weather and complicated construction may require the replacement of the whole kit even if you need to charge just one bulb.
It is pretty simple. All types of lamps for your vehicle is specified in the car's manual. That means H7 lamp will never fit into the socket designed for H4 lamp as they have different size and mount.
Though more often than not, we have no paper manual at our disposal, might be lazy enough to grab it, or finding the right information there can take ages and requires good nerve. To save your time and ease the process, we have digitalized this information and created the bulb replacement charts for all cars classifying them by make, model, year and trim (if need be).
The higher the color temperature, the better is a popular myth. In reality, here are the optimal color temperatures for different kind of lighting systems:
The specified color temperatures simulate the daylight as much as possible to increase visibility at night and nasty weather.
The total power capacity of a car's electronic devices determines the load on the generator. When choosing the replacement light bulbs, the power of new aftermarket lamps should not deviate much from the factory specs.
