Step 1>

Open a new document 300x300 pixel. Fill it with white. Set the foreground to white. Now from the Layer panel choose Channels. Make a new channel. Select your Line Tool and make these settings.

Now go to View > Show > Grid. Now start drawing. After you made the stroke, fill it up with white.

Go to Filters > Gaussian Blur and enter size 4.5 or 4. Now go to Image > Adjustments > Levels. 80/1.25/125.

Now turn back to the Layers and make a new one. Select > Load Selection. Pick Alpha 1 and ok. Fill the selection with red (#e61e35). Go to Layer Style > Inner Glow.

Now take your line tool again. Set the size to 3 px and make a little line.

Go to Layer Style > Outer Glow.

Add some rectangular at the bottom and the final product should be this.

Step 2

Now duplicate the layer so that you have other lights. Go change their color go to Image > Adjustments > Hue/Saturation. Play there and you will find other colors. Then adjust the outer and inner glow and there you are.
On your right Panel, at the bottom, you have a button that will send the picture to ImageReady. Hit it. Before you hit it, make sure you have selected the layer with the first light. Now you are in ImageReady.
In the Animation Panel you have the first frame. Set the Delay to 1 sec.

You have a selection around the light that is selected. Go to the other layers and disable the outer glow. You do this by clicking on the eye.
Now make a new frame from the little arrow you have in the right up corner of the animation panel. Now you have a selection around the second light. Enable the outer glow of this one and disable the outer glow of the others. Do the same thing with the third light.

Now go to File > Save Optimized As…
The final result is this.
