No modification necessary, no hyper flashing, no errors, no problems!
If you've got the OEM LED package, they're still an upgrade since your stock signals don't have the badass sequential function OR the better looking smoked housing. These Jeep Wrangler LED turn signal housings are designed to work without any special wiring. Stock Sucks: No doubt the new Jeep JL is the bigger, badder, more refined Wrangler we've been waiting a decade for, and if you've already upped the ante with a lift, bigger tires, wider wheels, and more power, then it's time to ditch the stock lighting setup too.
