How do single bulb headlights work?
Single beam headlight bulbs such as H11 and 9005 work exclusively with one beam, either the low or the high beams. As such, single beam systems require two bulbs total, one to create a light beam for the lows and a second to create a beam for the highs.
Do both headlights have to work?
In most states, it is required by law that headlights must be used from sunset to sunrise. It’s also law that a motor vehicle (unless it’s a motorcycle) must have two headlights. Therefore, if you have a headlight burned out, it is possible (and likely even probable) that you’ll get pulled over.
What happens when one of the headlights is not working?
When one of the headlights is not working, the bulb of the faulty lamp may have burnt. The lifespan of bulbs is limited and this is greatly dependent on usage as well as magnitude of vibration they are exposed to. There is no way the tungsten filament in the incandescent bulb will not burn out.
How does a high beam light bulb work?
Get familiar with the fuses and relays that control your headlights. The headlight switch usually doesn’t control the headlight bulbs directly, but through one or more relays. The headlight switch powers a relay, which powers the headlight bulb. This protects the headlight switch from the high current used by the high beam headlights.
When do you rely on headlights to lead the way?
Whether you’re driving home from a late night at work or get caught in a rainstorm while taking the kids to school, you rely on your headlights to lead the way.
When do headlight bulbs burn out what do they do?
Every driver depends on their vehicle’s headlights to light their way in the dark and during rainy, foggy, bad weather.

Unfortunately, just like all other bulbs, headlight bulbs burn out eventually.
