Default mixing 18 and 20 gauge wires

this may seem like a stupid question but some friends say i can and some say i cant.
i just got a pair of cold cathodes and the power and ground wires are too short. they are 20 gauge and i went to walmart to get some to lengthen it but they didnt have it. i have some 18 gauge wire laying around, so would it be hazardous to splice 18 gauge to the 20 gauge?

Lol, no there would be no hazard what so ever. It's better to have one wire, but if you need to splice into its fine. The only reason splicing a new wire in is bad is there is another potential failure point. Just make sure you have good solid crimps, and don't ever use wire nuts. I've seen people who think wire nuts are great, but they are only good in a house where you have no movement. If its a long run it may be best to just use the 18 or 16 guage, 20 gauge is pretty small. What size cahodes and how many are you going to be running?
