Anyone know the light bulb number for the interior quarter panel light bulb, C4SZ-13776-?

I've pulled them both out and they are Taiwan bulbs with no numbers that I can find.

I'd like to find a brighter LED set for the interior to replace these but without the original number it is kind of hard to locate an LED model.

Anyone know?

 

Just take it down to the auto parts store, and they'll help ya out.

I *want* to say 1156, but that'd probably be wrong... been a while since I had those... and those were '64-5 Tbirds. (same assembly.)

 

NAPA said it is an 89 and their part number was BP89.

Searching for either I can't seem to find a LED version. I'd really like to get things a bit brighter in the back but still stock looking. I don't want to add a dome light but the one light under the passenger dash area and the two in the back with these bulbs just seems dingy not quite yellow but close.

 

If you haven't done it yet, those lamps will be brighter and whiter if you replace the plastic lenses. Here's a link to one suppliers' offering:
