Technology for headlights continues to evolve like something out of science fiction. Although halogen and LED are fast becoming dated, they're still the default and the norm throughout the auto manufacturing industry. Why? Which one's better? Here's our Lyons, IL Freeway Ford Truck Sales team's basic comparison.

Halogen Headlights

Halogen headlights are the most classic, dating back to the late 19th century and predominating until about the 1980s. Halogen is a classic filament bulb-like many in the lamps of your house. It contains a tungsten filament and halogen glass encased in a small tube of quartz. The filament glows when electricity passes through it. As the tungsten melts, halogen combines with it and redeposits the tungsten back onto the filament, prolonging bulb life and preventing interior discoloration of the bulb.

LED Headlights

LED stands for light-emitting diode. The diode emits light after electricity runs through a semiconductor and electrons recombine with electron holes. LED uses less energy than halogen and lasts longer. Halogen emits roughly 1,900 lumens for every 100 watts, while LED emits about 11,500 lumens for every 100 watts. As a result, LED is advisable for high beams, but in some instances, halogen still makes great low beams.
