I left town tonight and dad called to say I had no tail lights. I stopped and checked the book to see where the fuse is and couldn't find anything for the tail lights or parking lamps. I have brake lights, both rear turn signals and the tail lights blink when you lock it with the fob. The trailer socket shows I have trailer tail/marker working. Why don't my tail lights work?

It was a year old last week.

 

on my 2001 i have the same issue and it was a trailer tow fuse in the box under the hood check it out. It was a 15a that did it for me. I also had no running lights or dash lights along with no tailights. Hope this healped!! Good Luck

 

My trailer plug has all of its lights working.

 

If you have dimmed down your interior lights to far it dims your park lights.

 

" If you have dimmed down your interior lights to far it dims your park lights."

You have got to be kidding me. Seriously. Please tell me that's a joke.

Not only would that be a stupid design, but the dimmer for the interior lights is barely usable. I go from no lights to interior lights on with almost no control.

 

HAHAHAHAHA!!!!!

 

I second the trailer tow fuse under the hood. This has popped a couple of times on me over the years for some odd reason.

 

Trailer tow fuses shouldn't have any effect on the truck lights, only the trailer plug.

 

All of my trailer functions are fine. My dash lights are fine. My mirror marker lights are fine. My front marker lights are fine. My high and low beams are fine. The rear markers will blink when you lock the doors with the key fob. They don't come on with the lights. I haven't found any fuses for them as of yet. My dealer is really not helpful with diagnosing anything.

 

Had the same problem, the manual doesn't say which fuse is responsible for the taillight. After pulling about 40 fuses it turned out te be f30 15A (

Parking lamp relay, TT parking lamp relay

 

hi have tail lights not working on 2011 f150 they come on for few seconds then go out

 

I think the fuse is listed under running lights, same thing happened to my 2011 last winter.

 

hey Guys,

ok so here the things i lost my tail light the other day and cannot figure out why, i have checked all the fuses as well as check the connections under my truck as i did get stuck in the mud last weekend but everything worked after that. i also lent my truck to my father who towed a trailer, i have checked fuse #26 witch i believe is the trailer fuse as i read here that may cause it. but #26 fuse in my truck is a square fuse that is a 30amp, am i checking the right fuse or is there something i should check?

 

did you figure this out cause the same thing happened to my truck, im wondering what your problem was?

 

There is a fuse in the panel under the hood for them. I also had problems with my brake controller which may have caused it. I haven't had the problem since it was a week old 4+ years ago?
