Hello. I purchased new OEM LED chrome projector headlights from eBay for $2,400, and I also bought the wiring harness and OEM ballasts from a custom lighting supplier for $580. It’s plug and play with no wire cutting. All lights work, but when the engine is running and the high beams are turned on, they flicker/blink/hyperflash rapidly. I understand I may need to change a few settings in FORScan so the computer recognizes the LED headlights, but I’m not sure which values need to be changed. Does anyone know which parameters need to be adjusted and what they should be set to? I’ve already used FORScan to modify several functions before, so I’m comfortable with it. Thanks!

 

Hello, facakok - Welcome to the forum. I moved your post since it was in a thread that described a different problem. You're going to have to tell us more about your truck. What year, trim is it? Were the original headlights LEDs? Anything that will help the electrical experts here identify your systems are needed.
