Red flash for each network player when he gets hit

I am trying to make a multiplayer fps game. I want to flash a red gui texture for each player that gets hit by another player. I instantiate each player as a prefab. I tried to put the gui texture inside the prefab so that each player has its own red gui texture, but this doesnt work cause i cant see the texture after i instantiate it in the network.

For example when player2 gets hit by player1 i want to retrieve the guitexture of player2 and flash it in front of player 2. I hope u understand what i want to do.

Thnx in advance.

I am using this script for flashing the texure:

function Fade (start : float, end : float, length : float, currentObject : GameObject) { //define Fade parmeters
if (currentObject.guiTexture.color.a == start){

for (i = 0.0; i < 1.0; i += Time.deltaTime*(1/length)) { //for the length of time
currentObject.guiTexture.color.a = Mathf.Lerp(start, end, i); //lerp the value of the transparency from the start value to the end value in equal increments
yield;
currentObject.guiTexture.color.a = end; // ensure the fade is completely finished (because lerp doesn't always end on an exact value)
        } //end for

} //end if

} //end Fade

function FlashWhenHit (){
    Fade (0, 0.8, 0.5, GUITextureobjectname);
    yield WaitForSeconds (.01);
    Fade (0.8, 0, 0.5, GUITextureobjectname);
}

in the players health/life script (what ever gives it hits points and makes it die when they get to zero) add a variable (boolean) called showGui or something like that which turns on after the line that subtracts health. Then have your red flash drawn as a GUI texture (2D texture, not sure if GUI texture is the right phrase) across the whole screen which is only called when showGui variable is true.
