    Hi. Ive been a lurker for a while and gained a lot of info. Thanks everybody. Have an 08 pete 386 that is making me pull my hair out. All headlamps and marker lamps work properly except when lowbeams are on the highbeam indicator flashes constantly. Indicator stays on and works fine when highbeams are on just starts flashing when lowbeams are on. Ive swapped dimmer switch, headlamp switch, and instrument panel from known good truck. Checked bulbs and wiring and cannot see any problems. I dont have a matching "turn signal module" under dash the part numbers are different from my doner truck. I was wondering if anyone had any advice before I take the plunge and buy a module. Thanks for reading and any help.

    Your lowbeam light is out on one of the sides. Its using your highbeam @ low power to compensate.

    Mine does the same thing flashes and everything is working perfectly but you can click it to high beam and back to low beam one time and it stops...
    Maybe that will help some of you OCD people like myself because I cannot figure out the reason for this as is why I am on this page but no one has any answers here either
