Is "578" the correct interior bulb?

For the dome light that's above the rear seat? I'm getting conflicting numbers at different websites.

I changed the front ones and the foot well ones to LED and it looks awesome, now I want to buy one for the back. The fronts were "194" and I assumed the back was the same, but it's not.

Depending on the year of your truck, earlier model, gen 4 were a LED board and later models were a festoon bulb...can’t remember the size

Figured it out. I have these coming today.

They also just so happen to fit my 2002 Ford Explorer. So I'll swap those out as well.

Hopefully you like them, but amazon has a great return policy either way. Usually I want overkill daylight type of brightness, but I actually found with interior lights that I prefer the "warm/soft" incandescent that aren't super bright, as otherwise it kills your night vision right after they turn off when they are TOO bright. *shrugs*

Those may not be so bad though, as I had gone with a replacement that had wires going out to a whole LED board that you tape in with transparent double-stick.

They came. I installed them. They look awesome!

(I'm say "they" because I put the other 3 in my Ford Exploder, which just so happened to take the same bulb #)
