Troubleshooting your Light
If you're experiencing a problem with one of our products, we strongly recommend that you first troubleshoot your light. BLIAUTO does not sell or warranty ANY products on Amazon, eBay, or any 3rd party marketplace.
We’d like to think that every light we build is perfect. It’s certainly our goal. In fact, the vast majority of our lights are still in the field doing exactly what they’re supposed to do. But even with our high quality, there are going to be occasional problems. We stand behind our products, and if you have an issue, we will make things right.
The problem is, we get a lot of returns where the lights are okay and operate as intended. That means wasted time, effort, and money for everyone! We’d like to show you a few things you can check before you return a product to help determine if it’s a warrantable issue or not.
Faulty Operation
● Please note that reported failures are often the result of issues unrelated to our products. A returned product that is found to be functioning properly results in unnecessary costs to our customers—in both shipping and time. Before requesting a return under warranty, please take a few simple steps to ensure that the problem you are experiencing is the result of a faulty lamp.
Light will not operate:
● Bench Test. Remove the lamp from the application and test it using a power supply of the appropriate voltage. If the lamp functions properly outside the application, the problem lies elsewhere, and a return would not be covered under warranty.
● Swap with a functioning lamp. If another lamp of the same type is in use, switch positions and see if the problem follows the lamp. If it does, the problem is likely with the lamp. If not, the problem is likely somewhere else in the circuit.
Light flickers:
● Test the input voltage. Unlike traditional lights, which merely dim with low voltage, LEDs will flicker. Use a multimeter to test the input voltage (the application’s output voltage). Anything more than 1-2 volts lower than the stated operating voltage could result in flickering.
● Swap with a functioning lamp. If another lamp of the same type is in use, switch positions and see if the problem follows the lamp. If it does, the problem is likely with the lamp. If not, the problem is likely somewhere else in the circuit.
● Jeep owners: Flickering can be the result of Jeep’s PWM circuitry, commonly referred to as hyper-flashing. Ensure you have the correct lights for your vehicle and—if required—anti-flicker harnesses.

and how to troubleshoot your Jeep installation.
If the above tests continue to point to a faulty lamp, please reach out to your authorized dealer to start the warranty process.
Condensation vs. Water Ingress
It is important to understand the difference between water ingress and condensation.
Condensation is common in all automotive LED lights and is not a warrantable condition. More favorable weather conditions or heat from the light should evaporate any condensation that may form.
Pooling water and large droplets are indications of ingress and are warrantable—provided the ingress is not a result of abuse or misuse.
Warranty Process
We’ve structured our aftermarket business to empower the local dealers so they can provide the most effective level of support possible. If you have gone through the troubleshooting above and still find your light to be faulty, please contact your authorized Bliauto dealer where you purchased the product to start a warranty claim.
