What kind of bulbs are used for dipped beam headlights?
Single and dual filament bulbs. In some vehicles, the dipped and main beam lights are two separate bulbs. They may be contained in the same headlight housing, but one bulb is for the dipped beam and the other is for the main.
Why are my headlights not working in high beam?
If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.
What’s the difference between dipped and main beam lights?
Single and dual filament bulbs. In some vehicles, the dipped and main beam lights are two separate bulbs. They may be contained in the same headlight housing, but one bulb is for the dipped beam and the other is for the main. These are known as single filament bulbs, because each bulb has only one filament inside.
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.

Is the dipped beam light the same as the main beam light?

How does a headlight switch turn on a high beam?
In the same way that your headlight switch activates a relay to provide power to the headlights, operating your high beam control will generally activate a relay to turn on the high beams. In the case of dual filament headlight capsules, this literally sends power to the high beam filament.
Why do the headlights work when the lights are off?
When the lights where off and the engine was running the low beams worked because of the secondary relay that powers the lows beam automatically when engine is running (this was a requirement in my country, low beams turning on automatically when engine starts).
Why are my high intensity discharge ( HID ) headlights not working?
High intensity discharge (HID) headlights can also fail due to other associated components. Neither of the headlights work. The cause: Burned out bulbs, or an issue with power or ground. The fix: Check for power and ground, and fix if necessary. Otherwise, replace the bulbs.
Why are headlights not working but high beams are?
Corrosion, a bad ground, or some other issues can damage the sockets and disrupt the power flow to the bulbs. If only the sockets of the low beams are bad, it will cause headlights not working but high beams are.
Are there any aftermarket LED headlights that work?
There are boutique high-end outfits like Diode Dynamics specializing exclusively in aftermarket LEDs. And of course, eBay and Amazon are chockers with cheapo off-brand options. Unfortunately, for the most part, none of them really work correctly with few exceptions. Why would anyone want LED headlights?
Which is better led or incandescent headlight bulbs?
Everything else being equal, it seems like swapping power-hungry incandescent headlight bulbs for brighter lower-draw LEDs would be an upgrade on two fronts. Plus the “instant-on” effect and visual crispness of light that comes from LEDs is sharp and fresh. LEDs can give older cars modern styling.
How does a car headlights cradle of reflectors work?
Most car headlights are a lot more than just a bulb in a socket. A cradle of reflectors is shaped and angled so that light emitted from the filament of an incandescent bulb will be thrown down the road in a way that maximizes driver visibility without blinding oncoming traffic.
