 Why you should replace your car headlights?

If your car is a halogen headlight bulb user, you will find that your halogen bulbs will slowly dim over time. Frequent driving with dim halogen headlights on dimly lit streets and mountain roads can pose a great safety hazard to your driving. You need to update your halogen car bulbs with more advanced car lights. So how do you choose a premium auto lights? Most car owners will choose to use the very popular LED bulbs in place of their original lamps, but now there are a wide variety of LED products on the market, ranging from $10 to more than $100, which greatly increases the difficulty for those who choose to use LED lights for the first time. Next, we will bring you some methods to identify high-quality car LED lights, hoping to bring you some help.

How to judge the quality of LED headlight bulbs?

1. LED Chip:

  • Use chips from reputable manufacturers for better brightness, heat dissipation, and heat resistance.
  • Leading chip manufacturers include Osram, Lumileds (Philips), Nichia, and Toyoda Gosei.
  • Choose chips with better conductivity and heat dissipation for longer lifespan.

2. LED Lamp Material:

  • Metal-bodied bulbs, such as aluminum, provide better heat dissipation and durability.
  • High lumen output generates more heat, requiring larger heat dissipation volume.
  • Limited space in OEM headlights requires better heat dissipation materials.
  • High-grade aluminum LED lights offer better heat dissipation and overall stability.

3. LED Intermediate Substrate:

  • The thermal conductivity of the substrate affects the heat dissipation performance of the LED.
  • Copper substrates offer twice the thermal conductivity of aluminum substrates.
  • LED lights with copper substrates generally have a longer lifespan.

4. LED Light Fan:

  • LED bulbs with fans effectively dissipate heat, especially those with high power requirements.
  • Higher fan speed improves heat dissipation efficiency and extends bulb lifespan.
  • Choose a fully hollow lamp body design for better air circulation and heat dissipation.

5. Internal or External Drives:

  • The driver is the heart of the LED light, regulating its operation.
  • External drives provide better overall heat dissipation and lasting stability.
  • Choose bulbs with drives for optimal performance and longevity.

We hope that after reading this blog, you will be able to increase your knowledge of LED lights and give you tips for identifying quality LED products. Finally, don't forget to know your LED model number before buying LED headlight bulbs, you can take out your own halogen bulbs and check their numbers.

The following is a selection of high-quality LED products that meet the above description for the reference of car owners.

The following is a selection of high-quality LED products that meet the above description for the reference of car owners. Novsight N60 Series LED Headlight Bulb , which can provide 40,000 lumens of output. The brightness is 9 times that of ordinary halogen lamps. The perfect beam pattern can be focused on the driver's side without causing dizziness to oncoming vehicles, making driving safer. The fuselage as a whole is made of 6063 aircraft aluminum, which has a better heat dissipation effect. The copper substrate is used in the middle to quickly guide the heat generated by the lamp beads, and the thermal conductivity is stronger. The fan part adopts a hollow design, which is conducive to air exchange. The fan is a turbo fan with a speed of 12,000RPM/MIN. The drive of the bulb is external, which is beneficial to the heat dissipation of the LED lamp. Click here to learn more.
