Dash board lights

how difficult is it to replace the dashboard lights; is it pretty straight forward or are they sealed into the gauges or anything?
I’ve had the dash opened a number of times to replace speakers, radio and wire in a tachometer but, never bothered to look at how the gauges were installed. One of the bulbs on my Speedometer burnt out last night and I can only see half of the gauge at night so, figure this will be a great time to replace them all.
