I acquired a 2007 f150 crew and the regular beam headlights only work on bright....I welcome any sugestions on a fix

 

Have you by chance checked the bulbs? Although rare, it is possible to have both low beams go at the same time. Next, check your fuses.

 

I agree.. My wifes car had both low beams go out at the same time.. She called me at work and said headlights did not work.. Said I would look at it when I got home.

Come home, turn on lights, nothing. Hit the high beam and they work.

Decide to just get some new bulbs. Install them and both high and low working.

Never have I seen that occur before, but I did swap out the prior bulbs at the same time, when only one side went out before...

Good luck!
