So my Toyota Highlander license plate bulb was out and I decided to replace it. Replacement type was W5W. I pulled it out and thought, hmm this looks like a pinball bulb. I think I have a few of those laying around. Go digging in my spares and out comes a 12V 555 base bulb. did it work? Why yes it did!
I could have spent $6 to $20 at Autozone or I could shove a $1 LED pinball bulb in.
I just laid the old bulb and a spare bulb together for that first picture. The bulb I used had a few more SMDs on it.
