Recommended 9004 LED Headlight Bulb 1. What Is A 9004 LED bulb?9004 is an automotive light bulb specification, mainly used in the headlights of automobiles. Its bulb type is dual-lamp type, which includes the functions of high beam and low beam. 9004 bulbs typically use halogen lamp technology, providing higher lighting brightness and reliability. This bulb specification is more common in some older models, but with the development of modern automobiles, more and more new models use more advanced LED or HID bulb technology to replace 9004 bulbs. Overall, the 9004 LED Bulb is a more advanced, efficient, and longer-lasting alternative that provides superior lighting and lower energy consumption. 2. 9004 Bulb Specifications And FeaturesTech Specs: Take LA PLUS 9004 LED bulb as an exampleBulb Size: 9004 HB1Light Mode: Dual BeamPackage includes: 2 BulbsInterior/ External Driver: InteriorVoltage: DC 9-16VLight Power: 60W/set (30W/bulb)Luminous Flux: 6,000LM/set (3,000LM/bulb)Color Temperature: Bright White 6,000KLifespan: Over 30,000 hoursCertification: IP67 Water and Dust Seal, CE, RoHSFeatures1.360 Degrees Adjustable Socket for Adjusting The Beam PatternThe mounting collar is adjustable for freely rotating. Free to adjust the socket until it shines the perfect beam pattern. It's softly suitable for different light housing with different angles and the light pattern could be easily adjusted. Apply to both projector and reflector housing. No blinding the upcoming traffic or divers.*Due to the 360 degrees adjustable design, the mounting base can detach from the bulb.2.Amplified Flux Beam｜400% Brighter than HalogenThe aluminum parts are much thinner than the common ones in the market perform with no dark spot, are designed much closer to the factory halogen bulbs and provides 4 times as much light as than stock and excellent night time drivability by taking an amplified flux beam with 6 pieces flip chips on each bulb.3.Shorter Size｜Quick Installation Without StrugglingBuilt with a smaller/ shorter size than the common LEDs in the market without building an external driver, directly plug into the factory housing. The same design with the OEM halogen bulbs for easy installation and working well inside the housing without trouble.4.New Cooling System｜Better Heat Dissipation, Last LongerThe shorter size of these bulbs will leave more space between the dust cap and the cooling fans for better heat dissipation. New cooling system with a unique dual ball-bearing fan prevents the driving from the loud noise from the cooling fan, the all-in-one compact aluminum design brings better heat dissipation than common plastic design, and intelligent IC makes sure the LED conversion kits last longer. 3.Installation and maintenance of 9004 light bulbsHow to InstallationFor more detailed operations, please visit our BLOG: How to Install 9004 LED Headlight BulbsmaintenanceThe key to maintaining 9004 LED car bulbs is to keep them clean and in normal use, and pay attention to the following points:1. Temperature control: LED bulbs will generate a certain amount of heat, so make sure that the LED bulbs dissipate heat well. Make sure there are no objects around to block the heat dissipation channel of the bulb, so as not to overheat and affect the life of the bulb.2. Clean the bulb: Use a soft cloth or paper towel to gently wipe the surface of the LED bulb to remove dust and dirt. Avoid using cleaners that contain solvents or chemicals that could damage the bulb.3. Prevent touching the bulb: When installing or replacing the LED bulb, avoid touching the LED lamp beads directly, because the grease or dirt on your fingers may affect the heat dissipation effect of the bulb.4. Not suitable for high-pressure gas discharge lamp circuits: The operating voltage of LED bulbs is different from traditional high-pressure gas discharge lamps, therefore, do not use the 9004 LED bulb with unsuitable lamp holders or circuits.5. Correct installation: Make sure the LED bulb is installed correctly in the vehicle's light fixture. Follow the vehicle manufacturer's recommendations or owner's manual to properly connect the electrical connectors to ensure a stable electrical connection. 4. Precautions for UseWhen using 9004 LED car lights, there may be the following precautions:1. Installation method: Make sure the 9004 LED car lights are installed correctly on the vehicle. Connect power and connectors correctly according to the vehicle manufacturer's instructions or owner's manual.2. Voltage adaptation: Make sure the vehicle's voltage matches the rated voltage of the 9004 LED car light. If they do not match, it may cause the bulb to be damaged or not work properly.3. Leakage protection: Try to avoid exposing the car lights to water or humid environment for a long time to prevent moisture from penetrating into the bulb and causing short circuit and damage.4. Prevent overheating: Ensure that the heat dissipation channels of the 9004 LED car lights are not blocked and avoid installing LED bulbs in sealed spaces to prevent overheating.5. Temperature adaptation: LED car lights will generate a certain amount of heat. When replacing or installing, it is necessary to ensure that the bulb and surrounding components are not affected by excessive temperatures.6. Standardized use: Use LED lights in accordance with traffic regulations and turn them on synchronously with the driving lights to avoid using lights that are too bright and dazzling to cause trouble to other vehicles.7. Regular inspection: Regularly check the brightness and working status of the 9004 LED car lights. If any abnormalities are found (such as dimming, flickering, etc.), replace or repair them in time. 5. Frequently Asked QuestionsQ1: Are 9004 bulbs the same as H4 bulbs?A1: 9004 bulbs and H4 bulbs are two different specifications. Both 9004 bulbs and H4 bulbs are dual function lights that can be used for high beam and low beam. They use similar plug connectors and are also similar in appearance. However, their electrical specifications and lead arrangements are different. Regarding electrical specifications, 9004 bulbs are different from H4 bulbs in the power and brightness distribution of high beam and low beam. In summary, although 9004 bulbs and H4 bulbs are similar in some respects, they have some differences and therefore cannot be used interchangeably.Q2: What is the difference between 9004 and 9007 LED bulbs?A2: First, the electrical specifications of the 9004 and 9007 bulbs are different. The 9004 bulb uses a dual-filament design, with one filament for low beam and the other for high beam. The 9007 bulb uses a single filament design to switch between low beam and high beam through voltage changes. Second, the 9004 and 9007 bulb lead wires are arranged differently. In a 9004 bulb, the high beam lead is at the bottom and the low beam lead is at the top. Whereas in the 9007 bulb, both the low beam and high beam leads are at the bottom.Q3: What cars are 9004 bulbs suitable for?A3: 9004 bulbs are suitable for use in many automotive and motorcycle headlight systems. They are used in a wide range of vehicle models and brands, including but not limited to small cars, SUVs, trucks and motorcycles.Q4: What bulb is the same as 9004?A4: The 9004 bulb is a dual port bulb, also known as the HB1 bulb. Similar to the 9004 bulbs are the H4 bulbs in that they are both dual port bulbs, but not fully compatible between the two. H4 bulbs are model 9003 and are commonly used in Europe. Although 9004 and H4 bulbs are very similar in socket design, due to the difference in circuit voltage and wiring, you need to pay attention to their compatibility when using them.Q5: How many lumens does a 9004 light bulb have?A5: The lumen output of a 9004 bulb can vary depending on the brand and model. Typically, a common 9004 bulb has a light output of about 700 to 1200 lumens. However, as technology continues to advance, there are now also high-brightness 9004 LED bulbs that offer higher lumen output.
