As for the gasket that I made, it was one side sticky rubber seal and I placed it on the back side of the light where the original gasket belonged. This gasket did contact the cab and then compressed as I tightened the bolts.
I see that you used a type of caulk. It should do the job just fine if placed properly - may dry out and shrink tho during summer heat.

I've had the truck back to the dealer six times for water leaks since April of 2010. They've sent it to two separate leak specialists and I've been told the problem was fixed each time. I've had water pooling on the drivers side floor and soaked all the way back to the rear passenger door.

They "found and repaired the problem" and replaced the carpet because it was "nasty" and the truck was starting to smell musty and moldy. Also had an ant infestation under the carpet (they were apparently coming in through the firewall).

They've caulked the wiring harness coming through the front firewall and replaced all door seals on the drivers side door and said the problem was "solved".

I left the truck in my driveway to see if it was still getting wet. Last episode...picked it up Friday, it rained Sunday and the passengers rear seat was covered in water. Headliner was dripping and water running down the back window, rear firewall, and carpet was soaked. Underside of seat is visibly rusted.

I emptied the truck and parked it at the dealer service center that night with both sets of keys.

They say the rear brakelight was the problem...but will provide no guarantee that the truck will no longer leak. They've agreed to replace the carpet again, replace the headliner, etc.

I'm going to pursue legal action to have the truck replaced...love the truck, hate the mold and water. Ford says the truck is not eligible for their replacement program. I'm already having electrical problems with the headrest DVDs and will not continue to take the truck back to the dealer everytime it gets wet. The mold smell is obvious.

I have a hard time believing FORD thinks it is acceptable to have a brand new vehicle brought back six times in less than three months for the same problem. The service manager asked me to call Ford to get the problem elevated and to have a Field Service Engineer (FSE) came out to inspect the vehicle. The FORD rep on the phone told me to take it back to the service manager. An FSE did inspect the vehicle and agrees that the third break light is the problem and that the truck has had multiple leaks. The FSE will not provide a written guarantee that the vehicle will not leak or agree to replace the vehicle if it does leak again.

Anyone have any suggestions?

He said that one of the service guys has had to replace it in his own truck 3 times before this new light came out. I'm dropping my truck off at the dealership later today to get the new light put in.
