When it comes to longevity, LEDs hold a clear edge. This discrepancy can be addressed by adding a resistor, ensuring the car draws the same power from the battery but supplies the LED bulb with the appropriate voltage. Cars built for halogen bulbs might not recognize the lower energy draw of LEDs and might falsely interpret it as a fault. To put it in numbers, an LED bulb consumes approximately 80-85% less energy compared to its halogen counterpart.īut here’s the kicker: if your vehicle was initially designed for halogen bulbs and you wish to make a switch to LEDs, things might not be straightforward. LEDs shine brighter while consuming a fraction of the power. LED (Light Emitting Diode): LEDs produce light when electricity passes through a semiconductor. This method, while effective, is not particularly energy-efficient. As the filament heats up, it emits light. Halogen: A halogen bulb works by passing electricity through a tungsten filament surrounded by halogen gas. LED vs Halogen Headlights Power Consumptionīoth halogen and LED bulbs work on entirely different principles, affecting their energy consumption patterns. However, delve a little deeper, and the nuances of headlight technology start to shine through (pun intended). What’s the Difference Between Halogen and LED Headlights?Īt first glance, one might simply see headlights as those bright lights guiding us through the dark. Let’s dive deep into the contrasts between halogen and LED headlights to uncover which is the better choice for today’s drivers. From the familiar yellowish glow of halogen bulbs to the piercing white intensity of LEDs, consumers are now presented with choices they might not fully understand. With the rapid advancements in automotive technology, vehicle headlights have undergone a significant evolution.
