Hey everyone. I recently got a stock 85 4runner that I'm fixing up. Both tag lights were burned out. I checked both sockets and they both had power. Thought I'd pull up on the Internet what the size was so I could search for some led replacement bulbs. Numerous parts sites including napa and most every discussion I have seen referring to the bulbs show a 194. However, I have twist style bulb like 1156 but much smaller and I can't read the marking on them. They look to be factory installed and the lens covers say Toyota but everything I'm finding suggest I should have 194 wedge bulbs like my tacoma. And suggestions?

 

you mean license plate lights .

It is possible your sockets have been replaced

In the rust belt those housing rust out no telling what they were replaced with.

 

My '87 Runner has the brass socket license tag bulbs as you describe.
I think yours are stock.
I recently changed one out and I have the burned out OEM bulb at hand.
It is marked Koito 12v-7.5w.
I believe that the bulb type is #89.

 

Thanks!
