In the past, H4 bulbs served as the majority of the lighting in cars. These are referred to as bilux lamps. Simply said, this indicates that the bulb has two filaments: one for the low beam and one for the high beam.
One filament illuminates when the low beam is turned on, while the other illuminates when the high beam is turned on. When the low beam is turned on, the light cone is thrown in front of the vehicle; when the high beam is turned on, the light cone is thrown further ahead. The reflectors in the headlamp are precisely adjusted to the location of the filaments in the lamp. Halogen bulbs are now frequently used in modern H4 lights.
An H4 system has the following characteristics:
- The bulb housing of the lamp contains two filaments.
- In the headlamp, there is just one lamp base plate available.

Describe an HIR2 bulb.
CI1255 HIR2 halogen bulbs are frequently found on Lexus and Toyota automobiles. The UV-reduced HELLA halogen automobile bulbs are secure for use in contemporary headlamps with polycarbonate lenses.
What distinguishes high beam from low beam?
Headlights are frequently regarded as a design feature since they may give an automobile a unique appearance. But keep in mind that the purpose of headlights is not to enhance the appearance of your vehicle. Exterior lights illuminate the roadway in front of you, allowing other motorists and pedestrians to see you as well as where you’re going.
SHINING A LIGHT ON AN IMPORTANT SAFETY FEATURE
Driving in the dark has been a concern for people for as long as they have been using automobiles. That doesn’t necessarily imply driving at night. Even during the day, weather conditions have the potential to make the sky exceedingly black, and as a result, the streets. Headlights are especially important for drivers in rural locations where there may not be many streetlights.
IMPROVING A BRIGHT IDEA
Headlamps fueled with gas were once a standard feature on all vehicles. Then, the auto industry developed technologically.
- Halogen headlights outperform gas-filled headlamps in terms of brightness, durability, and heat resistance.
- LED headlights use less power and generate an even brighter light than halogens.
- The brightest lights on the market are HID headlights. Before you conclude that brighter is better and switch to HIDs, bear in mind that certain jurisdictions deem them to be too bright (each state has its own laws governing headlights)
Let’s now examine the use of high beam vs. low beam and when to keep to low beams.
HIGH BEAM VS. LOW BEAMOPERATIONALLY
The low beams are activated when you turn on your headlights. Simple enough, yes? Older cars generally had a foot switch on the floor to the left of the brake/clutch pedal that was used to turn on the high lights. The high beam control is located on the turn signal lever on more recent automobiles.
HIGH BEAM VS. LOW BEAMREACH AND INTENSITY
Low beams have a lower intensity and cover less ground in front of your vehicle. High beams have a high intensity and cover more ground.
WHEN TO USE HIGH BEAMS
- When more light is required (for instance, when driving on a rural road without any streetlights), switch to high beams.
- When driving in fog, use high beams with caution as the harsh light may be reflected back to the driver and obstruct vision. Because of this, some automobiles have distinctive fog lights.
- Of alert other cars to a hazard (such as a tree that has fallen in the road), flash your high lights. Please be aware that depending on the state, county, or city, utilizing and flashing high lights may not be permitted.

On a Toyota Corolla, how do you swap out the low beam headlight?
With the proper equipment, you can replace your headlights on your own, especially if you’re changing your high-beam lights. It may be simpler and safer to contact an auto body shop to replace your low-beam lights because doing so is significantly more difficult. The following tools are required for a DIY headlight repair on a Toyota Corolla:
- a headlight 9005 high-beam bulb
- a set of low-beam LED headlights
- the screwdriver (low-beam bulb only)
- socket 10 mm (low-beam bulb only)
Changing a high-beam bulb:
- Locate the bulb by opening the hood. The headlight assembly should be in front of it.
- Pull the lightbulb out by rotating it counterclockwise, pressing the tab on the electrical plug, then turning it clockwise again.
- Push the replacement bulb into the housing after inserting it into the electrical plug.
- Make sure your headlights are functioning correctly by testing them.
Since your entire light assembly needs to be replaced, replacing your low-beam lights is much trickier. To replace them, you’ll have to take the car’s grill and light assembly off. Once more, it is strongly advised to get your low beams changed at an auto body shop.
While hunting for new insurance shouldn’t take as much time as replacing your headlights, it often does. Your insurance should occasionally be updated and changed, just like old lightbulbs. Use the Jerry app to quickly locate and compare rates and plans from leading insurers.
Is H7 superior to H4?
The 180W headlight kit or two 90W headlights are installed in both headlights. They will provide highly effective, extremely bright light that will improve nighttime vision. The COB chip, or Chip on Board, used in the H7 headlamp is a relatively new advancement in LED technology. Compared to SMD, this makes it possible to create a denser light array that emits a clear, bright light.
The H4 LED headlights have a lifespan of up to 50,000 hours, whilst the H7 headlights have a lifespan of only 30,000 hours. Apart from the lifespan, both of them start to glow right away when powered on. They don’t always require a few minutes to reach the full brightness of it. Clear light will be produced by these LED headlights, and the spaces they shine into will be perfectly sliced. As opposed to halogen lighting, which typically has intense light in the center and gradually diminishes toward the edges.
These two headlights are water-resistant as well. The H4 headlight can endure rain or other damp conditions because it has an IP65 waterproof rating. On the other hand, the H7 headlamp has an IP7 waterproof rating, allowing it to be submerged underwater and still function well.
These two headlights will use less power than other headlights because they are both LED. Because of this, it is a better option in terms of long-term cost savings. These two types of headlights will undoubtedly give you the optimum lighting for nighttime driving, depending on which one best suits you.
H7 uses a high or low beam.
Autos have traditionally employed dual-beam bulbs. By changing the reflecting pattern, a single housing with a single bulb may switch between a high and low beam. So to say, a two-in-one light bulb.
However, more recent vehicles use two distinct single-beam bulbs for each purpose. The car’s headlights are then equipped with two bulbs, one on each side of the car.
Each of these beams uses either an H1 or a H7 bulb, as you would have guessed. And this is where the H1 and H7 bulbs differ from one another.
The high-beam light is produced by the H1, while the low-beam light is produced by the H7.
Both the H1 and H7 are single-beam lamps that produce a fixed beam using a single filament.
This headlight is mostly used on open motorways and at night on country roads; it is not always used.
The H7 beam’s shorter range makes it suitable for lighting the road ahead of the car.
Which vehicles will a H7 bulb fit?
You don’t have many options when it comes to the bulb fitting when buying new headlight bulbs. Your vehicle determines the type of bulb required. Several BMW, Audi, and Mercedes models, as well as many others, use H7 bulbs as headlights.
Using the bulb finder on our home page, you may identify the appropriate bulb fitting for your car. Check out our assortment of halogen H7 bulbs, which are ideal for headlights if your car needs them. We also have LED H7 bulbs if you want a fashionable aesthetic that is probably not street-legal.
