How do you replace your backup bulb light for a 1999 Lincoln Navigator?

If it is the same as my 2000 Navigator, you have to remove the inside panel of the tail gate, which is held on with hidden clips on the inside of the panel, a $10 tool at most automotive stores will assist in removing the panel. You must also remove the strap that is held on with 2 Philips screws. (it would have been easier for us if Lincoln had installed an access panel).
