Troubleshooting Guide: Why Aren't My Morimoto Headlights Turning On?

Did you just get your hands on a brand new set of Morimoto headlights and excitedly install them? You did all that work only to find they won't turn on? 

Before you panic or regret your purchase, there might be some simple explanations and straightforward solutions to this issue. 

This blog post will walk you through five common reasons why your Morimoto headlights might not work and what to do next.

Inspect the Connectors: Are Any Pins Bent?

One of the common reasons for Morimoto headlights not working might be an issue with the connectors. The pins inside could be bent or misaligned, preventing a solid contact. A quick visual inspection should suffice. Ensure all the pins are correctly positioned and making contact inside each connector.

Verify Your Installation: Could You Have Made an Error?

Mistakes happen, even to the best of us. It's quite possible that an error occurred during installation. Perhaps a plug was left unplugged or plugged in backward. It's always wise to revisit your installation steps, referring back to the guide to ensure you haven't overlooked anything.

Check Your Fuses: Could They Be Blown?

Your vehicle's fuse box could be another possible culprit. Any blown headlight-related fuses could result in your headlights not working. Inspect each headlight-related fuse and replace them as needed. Always remember that prevention is better than cure – it's good practice to have spare fuses on hand.

Compatibility Issues: Are the Headlights Suitable for Your Vehicle?

Not all headlights are universal and may be incompatible with all trim levels or model vehicles. Your Morimoto XB LED headlights might not be turning on due to an incompatibility issue. Before purchasing, ensure you've read Morimoto's compatibility guide thoroughly to prevent such headaches.

Manufacturing Defects: Could Your Headlights be Defective?

Lastly, if all else fails, you may have received a defective unit. If you've installed a pair and only one headlight is not working, try swapping the working headlight to the other side. If the issue persists with the originally defective headlight, it might be a manufacturing error. In this case, reach out to our customer service team to begin the warranty process.
