1157 is a dual element bulb, so that isn't it. Maybe an 1156? ...or 1142?

I'd just take what I have to the auto parts store, see what they say it should be, and compare that to what is in my hand. All I can say for sure is it's referred to as a "courtesy" light.

Weird. Both showed me when I looked at them. O’reilly’s listed several bulbs, all but one of which are incorrect but only the correct bulb is the right style so not hard to narrow down. AutoZone only listed two and one was not the right style so easy to pick the right one again.

It’s an 89 by the way.

Its an 89 size. They listed two different sizes for the car. But the 89 is the one for this car. I had to get the LED Blue bulbs off line. But Amazon was fast and they look great and no heat build up. I already changed the dome, and all the gauge lights.
