Your Oldsmobile headlights are essential safety features, so don't stint when replacing them! Go with a brand-name, recognized manufacturer. Other sites might advertise cheaper headlight sets from unknown manufacturers, but beware of the hidden costs. Purchasing from sites that advertise no-name, cheaper headlights means that you risk purchasing headlights with much shorter lifespan, or that will not match colorwise. When the bulbs burn out on these cheaper headlights, you may find it hard to buy suitable bulb replacements with the same kind of connectors. And are they selling poorly made retrofitted HID/Xenon headlights that promise to fit into halogen assemblies? These retrofits can produce unnecessary glare that creates road hazards. Instead, if you are interested in checking out the new HID/Xenon technology in headlights, look at our site's recognized manufacturers. These new HID/Xenon headlights are more energy efficient and draw less current from the battery. HID/Xenon bulbs use a mixture of xenon gas and halide salts to create a powerful light, with a bluish tint. Halogen bulbs use a filament that creates light from basic ohmic resistance across a filament (much like your basic, old-fashioned light bulb). Halogen bulbs rely on the 12v system in the car, while HID bulbs use a ballast. The new HID/Xenon headlights are much more powerful than halogen bulbs, so make sure that your Oldsmobile headlights are aimed correctly after installation.
