This way all you need is batteries and a off/on switch.
You only need one for each side too. If you solder the other LED in series with the blinking one, they will all blink.

So if you have 3 LEDs per side you buy 2 blinking LEDs and 4 non blinking LEDs. For each side you solder the blinking LED onto the board and in series you solder the other 2 LEDS. When the blinking one blinks, so will the others. The built in electronic circuit in the blinking LED will cut off any current going through it. As a result of that the other LEDs won't have current and will shut off as well. The end result is 3 blinking LEDs.
