These three bulbs all fit the same exact part. So this is a standard, t10 bulb and it's got a circuit board base, which means it's got a really tight, fit on some styles of connectors and on others. It'll just fit right into place. Easy one.

Really nice thing about this: is you can't really put it in backwards? It works both ways. This is our second bulb, and it too fits the same base, but this one even has like a little projector lens on the front of it, and the base is a little bit different. So, unlike the first one, you should never have any issue pushing it into place now last. This is a bigger bolt.

This is a t-15 and it also fits the same exact base, and it is by far the brightest bulb that i carry. That fits this style of connector my favorite way to use these is for reverse lights, but you could put them anywhere that there's also a t10 originally. Where would you put it?.
