Maybe you’re old enough to remember when headlights were essentially all the same on every vehicle.  They were so cheap and easy to replace, most people could do it themselves.  Those days are gone.  Now, headlights put out more and better light and are more efficient.  Those all contribute to better visibility for you, the driver.  But those improvements mean they’re more complicated and, therefore, harder to repair or replace. 
 
The new headlight technology basically takes two approaches, HID (High-Intensity Discharge) or LED headlights.  The LEDs put out a brighter light that can illuminate more of the road ahead.

Another new feature in today’s headlights allows them to turn when you turn your steering wheel.  The advantage is you can more clearly see where you are going.  They can dim parts of the beam so oncoming drivers aren’t blinded.  You’ll notice the difference most on dark, winding country roads.

Because these new headlights are far more complex than the previous generation, in most cases you can’t just unplug a lamp and plug in another.  Today’s headlights often come as a sealed assembly, and in some cases to replace it means taking off the bumper, the grille or the headlight housing. Some may require you to get a whole new assembly.

That, of course, raises the cost.  A new headlight assembly with LEDs, sensors and control modules may cost hundreds or even thousands of dollars, especially on high-end vehicles. Plus, the installation is complex.

That’s why when it comes to modern headlight assemblies, it’s best to have a technician diagnose the issue.  What you thought might be a simple burned-out leadlight could be any number of things, such as a wiring problem or a failed module. Having a professional diagnose it helps make sure you get the correct repair, and you won’t be replacing parts that don’t need replacing.
