Activated Ability [Invisibilty] Transparent Hats, Any help?

This script works 100% fine. But the thing is when I try and make the hats on the local player this tool is inside of, it only makes 1 of there hats transparency = 1. I am wanting to make all of the hats they have transparency = 1.

This is my script: [Line 22-24] & [Line 36-38]

local mouse = game.Players.LocalPlayer:GetMouse()
function Light()
    local player = game.Players.LocalPlayer
    local playerChar = player.Character
    local playerLight = playerChar.Torso:FindFirstChild("Light")
    if playerLight then
        playerLight:Destroy()
    else
        local humanoid = playerChar:findFirstChild("Humanoid")
    if humanoid == nil then return end




    playerChar:findFirstChild("Head").Transparency = 0.98 
playerChar:findFirstChild("Torso").Transparency = 0.98 
playerChar:findFirstChild("Left Arm").Transparency = 0.98 
playerChar:findFirstChild("Right Arm").Transparency = 0.98 
playerChar:findFirstChild("Left Leg").Transparency = 0.98 
playerChar:findFirstChild("Right Leg").Transparency = 0.98 
playerChar:findFirstChild("Head"):findFirstChild("face").Transparency = 1 
for i, d in pairs (playerChar:GetChildren())  do 
        if d.className == "Hat" then 
            d.Handle.Transparency = 1


wait(10)

playerChar:findFirstChild("Head").Transparency = 0 
playerChar:findFirstChild("Torso").Transparency = 0 
playerChar:findFirstChild("Left Arm").Transparency = 0
playerChar:findFirstChild("Right Arm").Transparency = 0 
playerChar:findFirstChild("Left Leg").Transparency = 0
playerChar:findFirstChild("Right Leg").Transparency = 0 
playerChar:findFirstChild("Head"):findFirstChild("face").Transparency = 0 
for i, d in pairs (playerChar:GetChildren())  do 
        if d.className == "Hat" then 
            d.Handle.Transparency = 0



script.LocalScript.Disabled = true
wait(0.000005)
player.PlayerGui.InvisibleAbility:Destroy()
    script:Destroy()

                    end
                end
            end
        end
    end
end


mouse.KeyDown:connect(function(key)
key = key:lower()
if key == "e" then 
Light()
end
end)
