Avoid using harsh chemicals or abrasive materials on the bulbs or lenses, as this can cause damage.

7. Troubleshooting

Flickering/Error Warning

For some sensitive vehicles (e.g., Jeep, Chrysler, Dodge Ram, GMC, Ford), flickering or error warnings might occur when changing to LED bulbs. This is often due to the vehicle's Canbus system. Please contact us for proper decoders/resistors to resolve the problem.

No Light

1. Check to make sure all wires are connected well and fuses are functioning correctly.
2. If only one bulb works, swap the left and right side bulbs to confirm if it is a Canbus problem or a defective bulb.

Light is Dim

Check to make sure the bulbs are locked into place securely and that the LED chips are clean and intact.

Conditions Beyond Warranty Scope

• Canbus Problem: Some vehicles equipped with a Canbus system may experience issues like light flickering or error warnings. Connect suitable decoders to solve these problems. If decoders do not work, you may be eligible for a full refund.
• Installation Problem: Some vehicles may not be able to install the bulbs due to limited installation space.
• Natural Disaster: Damages due to irresistible natural disasters like earthquake, flood, etc., are not covered.
