2007 JK Sahara unlimited. Stock (at the moment). Purchased Trucklite LED lights and pulse width modulation adapters. Installed easily. Now when I turn on the headlights, there is a 2 second delay before any lights come on (including the parking lights). Once the headlights are on, they start blinking off and on for 2 or 3 cycles of 2 seconds each then go out. Same with high beams. I tested with ignition off and the lights stay on until I get bored and either switch them off or start the engine again. I searched and did not find a good solution (might not have searched for the right term). The jeep behaves just fine with the original lights. I thought I got a bad set so contacted Quadratec who promptly sent me another complete set. Same behavior. Do I have a bad headlight switch, bad batch of lights, a computer problem, or what? Any thoughts on additional diagnostics?
