I got them on today. I was always leary about them leaking in the rainy weather so when I put them on I put a bead of silicon all the way around the bottom of the lights. That should insure no water to get through. My question is since today I got them installed, and tomorrow I plan on wiring them up. How do I take the A-Piller plastic off, I see there are two screws holding it on but by the looks of it I need to take the dash pad off to get it off, Or can I use a coat hanger and fish it through without taking it off? And once I get it through what wire does it get hooked to, I want it to come on with the running lights. I just want to insure I get it wired correctly the first time...
BTW yes thats my girl after she got done helping me fish the wires into the cab...
Do you want them to come on w/o the lights on or when you turn the lights on. If the first one then (I THINK!) you should tap into the bottom left fuse, its cold outside, just got back from baseball, and dont wanna go check for you. When i wired up my tack i led it directly to this fuse because i didnt know which one was lights or not. Hope that works!!
What I did was open the hood go to the drivers side front fender marker light, tap in there. When the markers come on, the cab lights will too.
Three points I'd like to mention....
1. Those are the wrong lights for the year truck, (the longer "rectangular" lights with the light grey plastic base) are year-correct.
2. The spacing is incorrect for the year too, all 5 should be evenly spaced, with the length between any 2 (which is equal) is divided by two' That is the distance in the length from the first light to the rain gutter. (or the last light and rain gutter.
Example: (but to correct numbers for placement) 6" 12" 12" 12" 12" 12" 6"
The center light is on the centerline of the cab roof.
3. Silicone sealant is corrosive to sheet metal (and perminent) You should use nothing, cause the foam pad is the gasket, or Vasiline is a good and removable "sealant"
Not being critical, just helping for year-correct Fords.
I'll post a photo of my '86 Stepside later.

1. I never said I was going for the OEM or correct style lighting.
2. To be DOT compliant the way I did mine are correct.
3. How can it be corrosive when cured? I used the silicon for an added layer of protection.
And Thank you Franklin, thats the answer I needed.
That was my post I believe. It seems like my early model lights are a little too long for some reason, and they don't quite fit the profile of the roof. I'm a bit perplexed by thx as its the same model year cab and lights.
I was going to silicon mine too, but now you have me wondering. Although the foam seals are in good shape, they still don't seal the light against the roof line.
The five eveny spaced are DOT correct too, (and year correct) The "grouped three" are required on the rear of "big trucks"
Silicone has a corrosive ingredient in it (even after curing) This is why any auto repair/paint shop will tell you NOT to use silicone on windshield leaks. and seam sealer is used in metal panel joints (along with being paintable)
If you ever try and repaint the truck, any silicone accidentially left on the roof or anywhere on the truck will mess up the paint job.
Page 3, 11, 12 and 17 on the original 1986 F-150 saled brochure show the correct light and correct placement of the cablights.
They are quite DOT compliant for that model year.
You can get different sealers if you want to use something. I know Lowe's has this roof sealer in a caulk gun tube now, but it's not the latex stuff, and it's not the tar based stuff. It's a urethane type sealer, and though it's a little expensive, and stinks too, it really works well. I believe my local True Value hardware store also sells some called "clearthane" or something like that. It's very clear, and is not silicone based either.
But if you just put it on the paint under the light, I would not worry about it.
I have just been through the "three lights in the middle" thing too. Federal lighting rules state that any vehicle over 80 inches wide, has to have marker lights out at the corners, and have the three lights in the middle. I just built a trailer that is 96 inches wide, so I had to get special "over 80" tailights, and had to buy the three light bar for the middle.

That is correct Franklin, and as you typed "just made" that also makes it fall into 2008 rules and regulations.
1980 to 1986 trucks didn't have to follow this 'cause this "law" was not on the books then. Also I just finished my 1948 Ford F-5, (15000GWV) Back then cab lights were an option, and only 3 on the roof were standard. You can look in my gallery.

I just always thought the 3 grouped together was the correct for all years. Also i think it looks better so thats why it is that way. Would it really matter though?
It doesn't matter, they are really more for decoration since these trucks are not big enough or wide enough for them to be required. But my 1980 did have factory installed roof lights, and they were spaced evenly all the way across. I would not worry about it. I am thinking about mounting some on the visor of my 89, and I think I might put the group close together in the middle like you did.
