I discovered the hard way that the instrument cluster bulbs in my 2011, which probably applies to your 2007 as well, are a "grain of wheat" bulb + base, the Toshiba V-2. On my truck they were made as a unit, as were the replacements I found online. The bulb could NOT be removed from the base. Some versions of the V-2 had removable bulbs, but not the ones on my truck, nor those I found for sale. I replaced all of mine with the same thing last year, but had to get replacements from eBay.
The 194 bulb is common on older Rangers and on other Fords (ask me how I know). It is probably NOT what your Ranger uses. I believe the change from the 194 (or similar) to the V-2 took place around 2006.
If I'm right about your truck, the LED you find will have to have the V-2 base. Some online sources say the base only is Toshiba T5, which is black, same color as the ones in my truck. (Other bases have other colors.) The separate bulb for this socket is TSD74, but it is noticeably larger than the "grain of wheat" bulb in mine. So you're looking at new T5 sockets + an LED equivalent of the TSD74, quantity 10 of both if you're replacing all the bulbs including the turn signal and high-beam indicators.
Be warned that the T5 sockets seem to be in short supply. They're a little pricier than you'd think too.
Right now, in my quick and dirty searches, I'm not sure anyone actually makes an LED replacement for the TSD74 bulb. The smaller LED replacements for minibulbs also are designed to light at the end, with little light to the sides. That might not work well in the gauge cluster. This is probably the reason some others have said they were disappointed with LED swaps in some applications.
This might steer you in the right direction.
