Hello new hear i have a 2005 FX4 and found 3rd stop light has room for 2 more
bulbs. Has anyone added 2 more ? Also how can i get the sockets for them.

Great question, you have some options. Your third brake light. Post pics.

 

I've modded a few single bulb all red 3rdBL's with extra sockets for more bulbs... er,uh LED's.

I actually have some OEM 3rdBL bulb sockets from my full led conversions.

 

Hello do you want to get rid of the sockets? If yes please contact me at al.lafon@yahoo.com

thx al lafon

 

Don't know how true this is but i was told in WV your 3rd stop light has to
work or you can get pulled over for it?

 

buggmanHay who makes the battery posts you have in your photos?

 

Does the 3rd Brake Light have white lights on the side of the brake light ?

On my ’03 had the Cargo lights were there and the harness up to the lights was there but no sockets or bulbs.
I added the sockets and hooked the cargo lights.
Cheap harness from LMC will give you Cargo Lights IF you have the wiring at the light.

I then changed my Cargo Lights to directionals.

 

OK how hard is it to do directionals?
my 3rd light is all red but has back plate with 3 places
for bulbs i was going to tie all 3 as brake lights

 

You got to love stupid !!
We had rain here today some clown came around me
on the rjght side of the road got in front locking his tires
to turn left! almost took out him out! O yes he had a cell
phone in his hand too

 

You need two things:
One is either a 3rd brake light with the white side lights built in or one of Buggman's LED 3rd brake lights with the cargo lights on the sides.

Two - wires from your directional lights wires to the appropriate x-cargo lights.
(On my '03 they were under the driver's set).

I think Buggman might be working on a directional kit... Better ask him.

If he is not, ask some more questions.

 

Drop me a PM & we'll discuss

I should have a few sets of the stock bulb sockets that I can put together with some crimp connectors that will crimp right onto your existing wiring.

The battery terminals are some from one of my parts suppliers. I modded them to handle a couple larger wires. I have a couple more sets of them too.

I have done a couple led modded 3rdBL's with my turn signal mod... here's a LINK to my 3rdBL pics & videos @ photobucket.

The wiring isn't too complicated, especially for the trucks with 3 bulb tail lights. I haven't tested one with a 2 bulb tail light truck yet, but they should work just the same.
You'll need to tap into both left & right side turn signals wiring to run into the cab, up to the 3rdBL and connect them to the outer red lenses' bulb sockets (or to my modded led 3rdbl wiring).
