My Headlights/Highbeams wont turn off even when engine is off. Ive been disconnecting the battery to turn them off. Anyone ever had this issue? Id appreciate any advice

Is it stuck on highbeams no matter if the truck is running and the on off switch or the high low beam switches are cycled?

I'd probably take a look at the relay. Pull and swap it for another that's the same and see if it fixes the issue. U cud pull and check fuses, take the highbeams fuse out all together and see if other functions operate normally.

Do you have fog lights?

Any after market bulbs or LEDS?

No fog lights and no aftermarket bulbs. Where is the relay located?

Had similar problem 2007 ford f150 xlt 5.0 liter, ended up replacing my turn signal switch out, solved my problem. Hope this helped.

The relay should be RO3. Look at diagram on fuse box cover for location. You should be able to swap it with RO2 to see if that corrects the problem. If so you need a new relay.

It is the turn signal stalk.
The "flash to pass" is stuck on. Try pulling back on the stalk, then pushing inward on it, then release it while holding it in.
My Brother in laws '04 was doing this, and this got it to turn off. Still have not fixed the issue, but at least the high beams are not always on.

This video shows the problem and how to fix it (or you can replace it with a new one, around $80).
