![]() The reason? Halogen isn't exactly synonym to efficiency and, to better understand why, we'll explain how such a light bulb works.įirst of all, it is made of a glass envelope capable of resisting very high temperatures, plus a gas, usually a combination of argon and nitrogen, along with a tungsten filament. However, halogen bulbs are becoming the second option for more and more car companies around the world. Basically a halogen light bulb has a lifetime of about 1,000 hours under normal conditions, while replacement costs are usually very low comparable to the other types bellow (around 30 bucks for a decent set). HALOGEN HEADLAMPS Halogen headlights are currently the most popular in the automotive world and, in case you're wondering why does this happen, it's mostly because of their primaryĪdvantage: they're simple and cost effective. So, let's take one at a time and see what this is all about. Some of you will agree with our statements, others won't, but either way, each of the four types of headlamps has its very own pros and cons. We'll thus try to discuss the advantages and disadvantages of each of them, although people generally believe, and it sometimes happens to be true, that the newest is also the best. We won't talk about the headlamp history today because we already did that, but instead we'll try to focus on the four major headlamp configurations of today and see what they're up to. Laser headlights is an example, but before discussing them, we have to go through more common systems available for a larger use. Furthermore, researchers are continuously working on the whole "headlamp" idea, trying to find new breakthroughs that would obviously make their products better than the rivals'. Although the whole automotive industry uses them, only a few people actually know how they evolved from simple acetylene lamps in the 1880s to very complex LED assemblies nowadays.
