You always want to splice with the same gauge or larger. If you had say 20ga wiring, splicing with 20ga or 18ga is acceptable. If you have a lot of solder joints right next to each other, it's best to stagger them to reduce the stack up height.

If I'm not mistaken, the headlights have larger ga wiring than 18. They should be 14-16ga as they see quite a bit of amperage.
