So i recently just converted to the hella headlamp conversion, with DDM LED bulbs, I love these lights, 6500k so a nice bright white. Anyway, they run perfect while the car is on (and i have searched for this problem) but when i shut the cherokee off mid day, or at night, the lights stay on for 2 min. or so, then when they are supposed to shut off they start to flicker and there is a loud buzz under the driver side dash, I read some were there might be some type of low voltage leak but not sure, thanks in advance COOP

Sounds like the Sentry Module (Headlight Delay). Majority unplug or bypass that feature for the same reasons when converting to LED headlights.

 

And, this should help you find it:
