Do we need to apply any additional settings to enable 150ft? Extra 50ft for the second pack is not lighting up.

Thank you for your question.Please find below a series of troubleshooting steps that may help resolve the issue: a. Please ensure that the adapter is functioning correctly. For the US adapter, a faint green light near the output on the front of the adapter indicates proper operation. b. To set the logo, navigate to the product details page and select the icon located in the upper right corner. c. Confirm that all waterproof connectors between the light strings are securely fastened. d. To reset the entire product set, press and hold the control box for at least five seconds. e. If a particular string of lights is not working, try connecting it separately to determine whether the issue is isolated to that string. If you have completed these steps and continue to experience difficulties, we kindly recommend reaching out to the customer service team of the platform where your purchase was made to take advantage of their warranty service. Please rest assured that we remain committed to supporting you throughout this process and are dedicated to ensuring your satisfaction.
