I purchased these at Walmart but they didn't light up for me. I currently have 15w188t bulbs. Am i doing something wrong? I was really excited to hear about these.

Sorry I replied the wrong size earlier. I currently have F15T8 bulbs. The instructions indicate they replace t8 bulbs.

This past year I replaced the 4 foot fluorescent lights in my shop with LED tubes.
I had one bulb that would not light up. On a hunch, I removed the bulb, flipped it end-for-end, and re-inserted it. It worked! I tried this on some of the others with the same results. The bulb had to be installed in a particular way. I did not find that info in the instructions with the bulb. It was a lucky guess? 
So, you might try flipping the bulb and see what happens. No guarantee, but it is an inexpensive experiment.
Also, were both bulbs installed at the same time? A missing bulb may also be the culprit.

LED lights
I replaced all 10 clearance lights with LEDs I bought from WISH.com. $4.00 with free shipping. Took about 4 weeks to get them but they work great and are as bright as the 1156s I replaced. Also bought several others to replace the interior lights. Tail, stop and parking lamps are next.

Answer for the 12v or 120v questions
The ballast for the fixture is what determines the voltage of the lighting. Check the label on the ballast and see what voltage it says also that label should tell you how many lamps (tubes) it is rated for 2,3, or 4. It doesn't matter what voltage the fluorescent bulbs says because the ballast increases the voltage from low to high to power the light. But the input voltage to the ballast must be correct for it to work right.

LED 18” Replacement Lights
Forget the bulbs and use LED strip lights, see how to do it at the following site.

You really don't want 110V light fixtures in any motor home due to the inefficiency in energy usage. Inverting 12V battery power to 110V light fixtures is much more of a strain on your batteries. It is most energy efficient and easy on your batteries to have direct 12V LED lighting working off your 12V battery voltage.

This works great. I did it to ours, but also left the fluorescent tubes hooked up. I can switch them on or off with a switch on the light. The LED strips come on with the wall switch.

Flicker LED’s
Tried your idea and swapped out the fluorescent bulbs in my 2000 Minnie. Both new bulbs had a constant flicker. Not a bad flicker but slightly noticeable. Enough to annoy. Did you experience this?

I understand the ease of changeover, and forgive my naivety, but if you just plug in the replacement LED bulb without removing the original ballast, effectively wiring in the LED "downstream" of the ballast, aren't you still energizing the ballast, thereby negating the benefits of going LED in the first place?
I mean, if I am understanding this correctly, two points of higher energy usage are the ballast, and the fluorescent bulbs. And except for changing out the LED, you're still using energy to run the ballast, correct?
