504 Bulb
Instrument panel bulb for the speedometer and tachometer, later superseded by 504L.
This is the 504 bulb, the small instrument bulb that lights up the speedometer and tachometer faces on the later machines in our catalog. It shows up in the electrical component listings alongside other panel and warning-light bulbs, doing the job of backlighting the gauges so you can read speed and revs at night.

Our records show this number was later replaced by 504L, so if you're working from a newer parts book or ordering from a supplier list and see 504L instead of 99-7050, that's the same bulb under its current number.
It's a straightforward wear item — bulbs burn out, and when one of your instrument lights goes dark this is the part to pull and replace. Confirm you're matching it to the right socket in your instrument cluster before ordering.
