I have a 95 ranger the signal lights are acting funny When the head lights are on and I turnthe signal on and step on the brake the back goes and the front flashes real fast when the headlights are off they work till I press on the brake then they go out Can anyone help me with this

 

based on your description its more than likely a bad ground. Id start by checking all the bulbs and their associated sockets first. If they check out ok, I'd look at the main ground G200 (ground for rear lighting). Unfortunately my sources do not reference the location for 1995. It might be somewhere on the rear frame member or inside vehicle floor on the left hand side (under carpet) next to where the wiring goes through the cab to the rear. If the grounds check out ok, then its more than likely a bad multifunction switch.

 

It's funny with grounds... lose the ground on one light and it can affect another.
If the front and rear light socket grounds are ok, check the Multifunction switch.
I had a 95 that the directionals would screw up, some of the time, I did find a ground wire bad but it did not help, what I found was the Multifunction switch in the steering column had one pin loose, fixed it and everything was ok again.
