Recently picked up a new rig (97 F250), and still trying to get a few quirks worked out.
Previous owner replaced the stock headlights with an HID unit. Overall, I like the lights. A lot brighter than other trucks of this era I've owned.
My issue is, when running high-beams for extended periods of time (something I do when cruising my local logging roads at night), the lights begin flickering on and off, and eventually stay off. If I switch back to low-beams, no issues. Lights stay on regardless.
I've checked the fuses, and everything seems healthy there. It seems to me that the previous owner may have installed bulbs that are too 'hot' for the wiring. While it hasn't been enough juice to blow a fuse, it seems like it heats up enough to short out. If I turn the high-beams off for a few minutes, they'll stay on for a while after. Road conditions don't seem to have any effect on it, so I doubt it's a loose wire. They'll do the same thing running down a smooth highway and bouncing down an access road.
Anyone with HID's running into this same problem? I'm at a bit of a loss.
