Today, we tried to install an H11 HID Conversion Kit and we encountered an issue of it not lighting up, but we quickly found a solution that fixes this. The most common issue that causes the HID to not work is that it doesn’t get power. We all know that we have to check the polarities, but what if the HID doesn’t even receive power? Before you can even check the polarity, you have to make sure that the connector and the adapter are snapped in together properly. What we encountered here is actually a textbook issue because the adapter wasn’t completely snapped in; therefore it doesn’t even receive power.
1.) One of the reasons why it sometimes doesn’t completely snap in when you try to connect the adapter to the connector is that the stock wire is hidden all the way underneath, making it difficult to get a firm grip on both parts to snap the connector.
