LED bulbs for Kubota L4200?

[griesheimer]

The brake warning light just died on my Kubota L4200-GST instrument panel. My parts manual says the replacement part ID is 38240-3147-0. While I have the panel out, I'd like to replace the instrument bulbs with LED. I'm guessing T10 size, but that's just a guess. Can anyone point me to an equivalent LED bulb?
Thanks.

Take your bad bulb to autoparts store and do a stare and compare of base size and voltage from those on display board...
