What you need to determine is the package form/size and the LED colour.  Probably even the latter is not critical.  Then you can obtain replacements through any electronic component dealer.

Through-hole LEDs will be described by their optical housing dimensions.  Circular ones are typical, so measure the diameter.  Then check whether the top surface is hemispherical or flat.

Small surface-mount indicator LEDs (not the larger ones used for lighting applications) will usually be described by a four-digit package code that is common to resistors etc, and simply describes their width and length.  This shouldn't be too hard to determine.  You then only need to remember which way round to fit them.
