I’m not sure if it’s just me getting older or my car, but it’s getting harder and harder to see the road while driving at night. It’s one thing to make sure luxury items like your Car Radio or Car Navigation System are working, but it’s even more important to maintain parts that affect your safety. Headlights begin to dim over time, and as the days get shorter in these winter months their brightness becomes even more important.
There are many different types of headlights such as incandescent, halogen, and xenon. Incandescent bulbs are the more traditional bulbs and tend to dim faster as the filament inside evaporates over time. Xenon bulbs use newer technology, specifically the HID (High Intensity Discharge) xenon bulbs which use two electrodes in a xenon gas-sealed bulb rather than a traditional filament. We are seeing these bulbs more and more in newer cars because the light they create is not only three times brighter than a halogen bulb, but lasts ten times longer. While three times brighter seems great for the driver, I can think of a time or two I’ve been blinded by an oncoming Audi or BMW, thinking their brights were on. Some headlights out today, such as bi-xenon, are so bright that they require self-leveling so they don’t blind other drivers on the road.
No matter which type of headlight your car uses, if you’re squinting to see the road at night you either need new bulbs or a pair of glasses. If you do notice your yellow-glowing halogen lights are much dimmer than they once were, be sure to change them both at the same time! It’s also fairly easy to upgrade them to xenon for that new, fresher look. Dimming headlights is a common problem but an easy fix, so don’t sacrifice your safety or the safety of other drivers on the road.
