Strange lightbulb-circuit tester?

Post by sixbennetts » Thu Apr 04, 2013 10:54 pm

Well, I knew that the guy who sold us our truck was a good guy. He tried to take care of everything before shipping it, and besides the rough starting when it's below 0°, we haven't had to touch a thing.

So I'm digging around in one of the bags with the snow chains, and wrapped up in rags is this little box with spare fuses, bulbs, etc.!

How thoughtful.

I know where all the bulbs go, except this one. It's too big for any socket I can find, and the prongs on the bottom look like they want to go into one of the relay slots.

Is it a relay tester? If so, how do you use it? Just plug it in and turn on the appropriate function, see if it lights up? Is it that simple?

Looks like a headlight bulb to me.

Oh, gotcha. Got confused because the truck has sealed beams. Couldn't figure out why he'd throw that in?
