Nested timers? Trouble with logic on multiple simultaneous timer ticks - vb.net

Question

I'm trying to create a simple visual example and the first step is having a column of boxes (panels) move across the screen. So far I've accomplished that, but I'm also attempting to have each panel blink a few times, individually, while moving. The effect should be a type of 'round robin' loop where the first panel blinks a few times, then the second, then the third, etc, etc and repeat.
I'm quite new to VB and so far I've only been able to successfully make either only one panel blink or all of the panels blink, not each one individually. Here's my code so far:
Public Class Form1
Public ticks As Integer
Public p(4) As Panel
Private Sub Form1_Load(sender As Object, e As System.EventArgs) Handles Me.Load
p(0) = Panel1
p(1) = Panel2
p(2) = Panel3
p(3) = Panel4
p(4) = Panel5
ticks = 0
End Sub
Private Sub tmr1_Tick(sender As Object, e As System.EventArgs) Handles tmr1.Tick
Dim i As Integer
If ticks = 1 Then
For i = 0 To 4
Dim randomValue = Rnd()
p(i).Top = 50 + 75 * i
p(i).Left = randomValue * 120
Next
ElseIf ticks > 30 Then
ticks = 0
Else
For i = 0 To 4
p(i).Left += 20
Next
End If
ticks += 1
End Sub
Private Sub tmr2_Tick(sender As System.Object, e As System.EventArgs) Handles tmr2.Tick
Dim i As Integer
For i = 0 To 4 'all of the panels blink at the same time..
If p(i).Visible = False Then
p(i).Visible = True
ElseIf p(i).Visible = True Then
p(i).Visible = False
End If
Next
End Sub
End Class
As of right now, all of the panels blink while moving across the screen in random locations, I'm assuming this is because the for loop responsible for the blinking is nested within the ticking timer, so for each tick it runs through the loop fully.
I'm a little stumped on what should be some very simple logic, but please bear with me as I am a novice.
Thank you for any and all help!

If I understand what you want, this would do it. They all blink now because they are all in the loop that occurs with each tick, this example changes each one by it's index in the array, and the index variable must be class level to retain it's value between ticks.
Private index As Integer
Private Sub tmr2_Tick(sender As System.Object, e As System.EventArgs) Handles tmr2.Tick
p(index).Visible = Not p(index).Visible
If index = 4 Then
index = 0
Else
index += 1
End If
End Sub
