Review on 🔌 iJDMTOY 9004 9007 HB5 to H13 9008 Headlight Conversion Pigtail Wire Harness Adapters - Compatible with 9007/H13 Retrofit by Craig Pham

These works. but the high and low beams were back. I had to pull back the headlights, remove the adapter and fix it. I did this by unplugging the top and bottom pins from the (cheap) blue connector and plugging them back in. It's easy to make, but there's no reason why they shouldn't come straight off the assembly line. I mean. You have a 50/50 chance of getting it right. They're also cheaply built as others have said. It's always a good idea to use a little Nolox or similar on connections and dielectric grease in connectors.
