FAQs

Q: The model of lamps I purchased is different from my OE halogen lamps. Can I get an exchange for the correct model?

  • The main reasons:
  • Amazon confirmed that the Fit system is not 100% accurate.
  • Your headlight assembly is not an OE part.
  • Please double-check the model of your OE halogen bulb. And contact our Customer Service for an exchange.

Q: The size of the lamps is not correct; they’re either too long or too wide, and LED lamps can’t be installed in the headlight assembly. How can I get proper-sized lamps for my car?

  • Some LED lamps are not in a 1:1 ratio with the OE halogen bulbs. The large base is for better heat dissipation and prolonging the life of the lamps. If the lamps are not suitable for installation, please contact Customer Service.

Q: Do you meet the five phenomena below?

  • Errors on the instrument panel;
  • The Lamp keeps flashing.
  • Can’t switch between high and low beams;
  • High and low beams reversed;
  • The Lamp does not turn on or off.
  • The above phenomena are decoding problems, which are mainly caused by the automotive computer failing to detect the correct signal. You can contact Customer Service to obtain the decoder and solve the decoding problem.

Q: How to adjust the lamps to 3-9 o’clock? I’ve read all the instructions, but still can’t find the method.

  • We recommend keeping the LED chips facing the 3 o’clock and 9 o’clock positions to ensure the best beam pattern and visual effect. However, it is impossible to adjust to this position for some vehicles. There is no need to worry about the position of the LED chips as long as the beam pattern is acceptable.

Q: The Daytime Running Lamps work incorrectly, it keep flashing. How can I solve the issue?

  • DRL and high-beam functions of 9005 bulbs are achieved through different power for many models, especially Japanese cars. No matter which LED bulb you choose, it is highly possible that DRL may not work properly. If you need the DRL function to work properly, please contact Customer Service. We will propose a solution according to your car model.

Q: After installing the LED lamps, I found my High beam and Low Beam reversed. Is there any way to solve this problem?

  • It is recommended to remove the lamp, rotate it by 180°, and install it again. If the problem still exists, please contact Customer Service.

Sealight S2S LED headlight bulb-FAQs

Q1. How do I install Sealight LED headlight bulbs?

Turn off your vehicle and locate the headlight housing. Remove the old bulb, connect the Sealight LED bulb, and secure it in place. Avoid touching the LED chips directly to prevent damage.

Q2. What is the correct orientation for LED headlight bulbs?

For single-filament bulbs, the LED chips must face side-to-side—at 3 o’clock and 9 o’clock. This ensures a proper beam pattern without dark spots or glare.

Q3. Are Sealight LED bulbs adjustable?

Yes. Sealight bulbs feature a 360° adjustable socket, allowing you to fine-tune the beam angle for your specific headlight housing.

Q4. Do LED headlight bulbs need alignment?

Yes. After installation, your headlights should be properly aligned to avoid blinding oncoming drivers. Use a wall test at 25 feet to adjust the beam height and angle.

Q5. How do I know if my headlights are misaligned?

If your lights seem dim, uneven, or if other drivers frequently flash their high beams at you, your headlights may need realignment.

Q6. What happens if LED bulbs are installed incorrectly?

Incorrect installation can cause poor fitment, wiring issues, or misaligned beams—leading to glare, reduced visibility, or even bulb damage.

Q7. How long do Sealight LED bulbs last?

Sealight bulbs are built with an advanced cooling system and can last up to 50,000 hours, far longer than halogen bulbs.

Q8. Are Sealight LED headlights legal for road use?

Only DOT-approved bulbs are legal. Always check product specifications and your local regulations before using LED headlights on public roads.

Q9. How bright are Sealight LED bulbs?

Sealight S2S bulbs deliver significantly more brightness than halogen, typically producing 6,000K cool white light for clear night visibility.

Q10. Can I replace my stock halogen bulbs with Sealight LEDs?

Yes, but most vehicles require a conversion kit or adapter to fit LED bulbs securely. Always confirm compatibility with your car model.
