Simple rain script. 'end' expected (to close 'while' at line 3) near 'elseif'?

It's a really simple rain script, however I'm new to this.

Here's the script

if game.Lighting.TimeOfDay > "04:00:00" then
for i = 1, 10 * 100000 do
	while true do
		wait()
	part = Instance.new("Part", game.Workspace)
	part.Transparency = 0.4
	part.BrickColor = BrickColor.new("Toothpaste")
	part.Size = Vector3.new(.5,1.75,.5)
	part.CanCollide = false
	part.Material = "Neon"
	part.Position = Vector3.new(math.random(-100,100), 100, math.random(-100,100))
	wait()
elseif
	game.Lighting.TimeOfDay < "04:00:00" 
	~= nil then 
		end
	end
end

The error is: 'end' expected (to close 'while' at line 3) near 'elseif' I can't seem to fix it.
