2X H15 Replacement Led Headlight Bulb Kit Error Free Canbus DRL Daytime Running Light 6000K White Light DRL Headlamp Conversion Kits Lamp

Just fitted them so it's too early for a proper review as the nights are still light. However, I installed one side and went straight forward butthe second side the bulb wouldn't light at all. Checked it and worked when connected it to a car battery. Put in original bulb again and is ok.I had to check further by adding a homemade wire setup and found the bulb must be wired up wrong inside the bulb.
