jeeze folks, the OP is talking about MARKER LIGHTS.. This is not brain surgery here.
Wire nuts in this case are OK as is crimping, soldering and any other possible method you can think of which conducts electricity..
However, I will say this.. The wire length available from the INSIDE is FIXED, keep that in mind with what type of connector you use.
If you HAVE to replace marker in the future cutting the WIRE off shorter is typically not an option..
That would lead me to use WIRE nuts rather than crimp or even solder in this case since breaking wire nut connections is much less destructive to the wire than removing a crimp or solder connection..
I personally would solder the connection but only if I know there is plenty of wire to be had in case of future repairs..
Alternately since it is a marker light you could crimp or solder spade connectors to the wires allowing you to plug in the light and future replacements will be easy..
