How do I update an older Airport Wi-Fi base station with a flashing orange light?

According to the advertisement it is actually a 'repeater' and not an extender meaning it will work with just about any accesspoint.

I will be curious to hear about your experience with using this 'repeater" with your AirPort base stations.

FWIW: The terms wireless repeaters and wireless extenders are often used interchangeably, but when actually implemented, there are some subtle, yet distinct differences:

• A wireless repeater is a device that receives a Wi-Fi signal from your wireless router or wireless access point and rebroadcasts it, essentially acting as a middleman to extend the signal range. It typically uses the same radio for both receiving and retransmitting the signal, which can cut your effective bandwidth in half due to the single-radio hop.
• A wireless extender, on the other hand, is more of a blanket term. It can refer to a repeater, but often it implies a slightly more advanced setup. Some extenders use dual radios (or even tri-band) so that one radio talks to the router and the other to client devices, which avoids the speed drop you'd get with a basic repeater. Some extenders can also connect via Ethernet or powerline, making them more versatile than a pure repeater.

If this "range extender" is a non-Apple device, it will not work to extend your existing AirPort base stations, especially if it is going to be a wireless connection between it and your AirPorts.
