While living without electricity in AK for several years we tried various lanterns and lamps and finally settled on oil lamps for lighting.

Ditto on what the others said, they should light without a problem.

Trim the wick! Some lamps have a round wick and only need trimming if the end has burned a little, which can happen if the lamp ran out of oil and wasn't snuffed out soon enough. If it's a flat wick it should be trimmed in a slight curve: higher in the middle and a little shorter on the sides. This will give an even burning flame that puts out the most light, in my experience. If the globe (glass chimney) is getting blackened then the wick needs to be turned down. Oil lamps actually put out good light if taken care of so trim the wick first, light the lamp, and gradually turn it up until it is giving out the most light without smoking or blackening.

In winter or cooler weather, turn the wick down, light, let it burn a little to warm the globe, then slowly raise the wick. Going from cold to hot can shatter globes which I learned the hard way. If you can find spare globes, get a set. (Pass on the frosted ones, reduces light) Pick up spare wicks at the same time.

Setting the lamps higher up gives better light and placing mirrors behind or under helps reflect light. Make sure the wick is well down in the oil. I have successfully sewn two short wicks together(overlapped) and the lamps still burned well.

Sorry for the length, I hope it's useful.
