Our records show this number was later replaced by 988R, so if your parts book or an older bulb in your instrument shows either number, they're the same physical bulb. If you're not sure which bulb your instruments take, pull the old one and check the base style before ordering.
We don't have much more detail on this one beyond what's in the catalog description. Worth keeping a spare on hand since instrument bulbs are easy to lose track of and easy to swap in.
