Why do my Hyundai Sonata’s brake lights not function?
The mechanic will bring a multimeter while inspecting the electric parts of your car, particularly the fuses and relays, to help them identify which particular part has failed. The mechanic will start by looking at the rear of the vehicle for any obvious damage, such as frayed or loose wiring and damaged tail light covers. The mechanic will next start to look at each component along the electrical circuit if there isn’t any obvious damage.
By checking at the fuses, the mechanic will start examining the various electrical parts of the car. He or she will take out the appropriate fuse for the tail lights to check if it is blown if they suspect a blown fuse. In such case, the mechanic will swap it out for a fuse that is properly rated for the amperage.
The mechanic should determine whether the unlit bulb is burned out if only one of the tail lights appears to be out. Bulb failure and replacement are inevitable over time. The mechanic will examine the unlit bulb’s filament to see if it is broken. In that case, a new bulb will be installed in lieu of the damaged one.
The mechanic will then examine the matching relay for the tail lights if it appears that the bulbs and fuses are in good operating order. The mechanic can measure the relay’s resistance using a multimeter. The mechanic will replace it and rewire it to the current connections if it is not operating properly.
The brake light switch should be checked by the mechanic if the tail lights appear to be operating OK but the brake lights are not. The mechanic will replace the old switch with a new one if the brake light switch is not reacting to the brake pedal. After that, the mechanic should ensure sure the brake lights are operational and responding to the new switch.
Any time a repair is required, the technician will see to it that all required work is done and that the new components work properly. A code reader/scanner will be used by the repair to erase any error codes that may have been set off by problems with the taillights.
How do I choose the right headlight bulb?
For information on bulb fittings, you can either get in touch with the company that makes your car or just check your owner’s manual, which should list all the fittings your car needs for each kind of light.
How do I brighten my headlights?
The brightest headlight bulbs are those made of light-emitting diodes (LEDs). They last five to ten times longer, use half the energy, and are 500% brighter than halogen bulbs. LED bulbs emit a clean white light, which vastly increases vision at night, in contrast to halogens, which produce a dim, yellowish light. For these reasons, switching to LED bulbs is the best method to drastically enhance the lighting systems in your car.
New luxury vehicles like Bentleys, Rolls Royces, BMWs, and Audis now outfit some high-end versions with LED headlights due to their exceptional performance. You’ve probably seen their blazing lights, which provide a strong white glare. The good news is that the headlights on your vehicle may be just as bright.
Using an LED headlight conversion kit, stock halogen headlights can be changed over to LED. Since the LED bulbs fit perfectly into your halogen housing and connect directly to your headlight power harness, the conversion process is actually fairly easy. Even your grandma can do this; it’s no different from simply changing a halogen bulb!
How do you tell whether your headlights are halogen or HID?
Factory HIDs, original HID headlights, and stock HID lights are all referred to as “OEM HID Headlights.” All of them mention the same thing: the car has HID Xenon headlights that the maker had installed.
Actually, there are three techniques to determine which lights are fitted in your car:
1. Parking your car in front of a wall and turning on the headlights is the simplest solution. HIDs typically resemble white, whereas halogens have a yellow hue. If your car has separate bulbs for the high and low beams, you can try comparing them or turn on the fog lights in addition to the headlights.
Please keep in mind that while having a blue hue, certain halogen bulbs still do not have the same brightness as HIDs.
2. In this situation, an owner’s manual for your car can be used. Sometimes, the instructions for changing the light bulb might be found there along with the bulb sizes.
3. Checking the vehicle identification number is an alternative (VIN). By using this VIN*, the dealer can look up your car and determine what kind of lights you have.
4. You can examine the headlight housing up close. Dynamic Xenon D1S/D2S, for example, may be written on the projector shroud or headlight lens of a HID headlight.
5. The final and most reliable technique is to remove the original bulb from the headlight housing. By doing so, you will be able to view the size that is indicated on the bulb base and buy the right set of lights.
Your headlights are factory HIDs if your car includes bulbs of the sizes D1(R/S), D2(R/S), D3(R/S), or D4(R/S).
Unless you have installed a different size bulb in your car, the OEM headlights are halogen.
In certain instances, the bulb that was removed from the housing does not resemble the lights in the images above. You might have aftermarket HIDs or LEDs in this situation.
Send us images of the light bulbs you need for your car if you’re still unsure of their type and size, and we’ll help you make the proper decision.
* If you are not the vehicle’s original owner, it’s possible that aftermarket HID lights have been added in place of the halogen bulbs. Before verifying this information, be sure the headlight assembly has not undergone any aftermarket changes or been replaced.
My left headlight is dim; what gives?
We have two quick repairs for you if your car’s headlight only produces about as much light as a flashlight with dead batteries.
Most do-it-yourselfers believe that their power feed or headlight switch is broken. But corroded ground wires are the main reason for dim headlights. See where the wiring harness joins to the car body by following it from the back of each headlamp assembly. Clean it as shown in the picture.
Another explanation is that as headlight filaments deteriorate, they leave a grayish-brown layer inside the bulb (See Photo). That coating can eventually cut visibility down by over 300 feet. Pull one of the bulbs out of your headlights to check the glass for any gray or brown residue if they aren’t as brilliant as they once were. Replace both bulbs right away if you find any to resume seeing more of the road.
My headlights are different in brightness; why?
Your lights are pointed at different heights. One appears to be brighter as a result of this. Although the dealer can quickly align them for you, you can probably do it yourself. Your lightbulb is pointed higher than the other.
What does H4 in the headlights mean?
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.
Why, even after changing the bulb, are my headlights still dim?
Some drivers are shocked to hear that burned-out bulbs are not the only reason why their headlights are fading. In actuality, the lenses themselves could be at fault. Acrylic is frequently used to make headlight lenses, which are the plastic portions that cover the bulbs. UV radiation and this substance are known to chemically react with one another. Your lenses may oxidize over time, giving them a foggy, clouded, or yellowed appearance. Oxidation produces an opaque shade that does not allow as much light to flow through as clear lenses do. Even if your headlight bulbs are brand-new, this will make them appear dim.
Simple headlight restoration services are the answer in this case. Your mechanic can handle lens oxidation and help safeguard your headlights from potential issues using tools fit for a pro and his/her experience. Read the entirety of our headlight restoration service instructions here.
How far up should you aim your headlights?
Your vehicle’s ride height can be subtly altered by suspension issues or a large cargo load, which may also cause one or both headlights to move. Your lights may become out of alignment as a result of a collision or running over a road obstruction.
Parking the car on a level surface and shining the headlights on a wall or garage door 25 feet in front of you can help determine whether the headlights are accurately aimed (some cars may require a different distance). For the majority of vehicles, the top of the low beam that shines on the wall should be at or just slightly below the height of the center of the headlight lens. You can anticipate that the light pattern will be lower on the driver’s side to avoid blinding other cars and higher on the passenger’s right side to highlight traffic signs. This should help you determine whether the beams on both sides are pointed in the right directions.
Another approach is to park the car five feet from the wall and then mark the wall’s vertical and horizontal light beam centers with masking tape. Reposition the car 25 feet back. The light beams should be around the same height both vertically and horizontally with the help of the tape line.
For adjusting headlight height, vehicles typically feature a screw or bolt on the headlight assembly. Some vehicles additionally include a screw for adjusting horizontal aim. A bubble level is also included in some cars to aid in modifications.
Without taking apart components like the battery, you might not have much room or even be able to reach the adjusters on some vehicles. Additionally, the vehicle must be perpendicular to the surface you’re shining the headlights on, be on properly level ground, and have no damage to the suspension system, flat tires, or baggage that would impact the ride height.
The owner’s manuals of many vehicles offer scant or no advice on headlight aiming. Ask a repair business to check if you’re unsure. A dealership may inspect the headlight aim and align it for free if the car is still under the basic warranty.
