Help me Indentify a Light

[fender5]

So this bulb came out of my third brake light on a camper shell. There are 3 like it and one of them shattered, so when I went to replace it low and behold it is impossible to find. So anybody got any great ideas on where to find this online or in store? (I already checked radio shack, 2 auto stores, home depot)
Sorry the picture is blurry, essentially there is a looped piece of metal on either side connecting it. Thanks!

That looks like a standard 80's-90's Ford Dome light bulb. it's about 1-1/2" long?

sounds like a 212 blub to me

best way to get it replaced is as follows

go to an auto parts store
make sure to bring the bulb
either go to the bulb isle and look for one that is similar
or
show it to an employee and ask for help(they dont mind, really, i am one of them, it is alot easier than doing 8 million returns because the customer diddnt ask)
