Those look like MES (E10) base bulbs so wide variety of LED equivalents available in huge range of colours and brightness. Should be fit and forget in terms of longevity. Pot luck as to how they work in illuminating your instruments though. You could change all instrument bulbs to match though. Bear in mind some are a little taller than OE filament bulbs if clearance is an issue.
Don't be tempted to replace charge warning with LED equivalent though without being aware these need to be shunted with resistor (47Ω) of appropriate wattage to simulate that of OE filament bulb.
