How to replace an instrument cluster bulb??

[jscpch]

The bulb which illuminates the total mileage, trip mileage and outside temperature on my 1994 S280 has failed so I can only read any of those if the sun shines on the dash.
I can see a small hole on the right side of the cluster which is presumeably for some release tool.
Is it a possible DIY job or is it one of those simple problems that costs a packet to sort out?
Thanks in advance for any advice.

The instrument cluster can be pulled out with the hook or in some cases pushed out from the rear

The Lamps are 2 watt

Thanks again Malcolm. Do you ever rest, eat or sleep?
