Any recommendations would be appreciated. I don’t want blue ones. As an airline shift worker, blue light is my enemy.
I’ve started to look on amazon but I’d like your input.
The minimum size of the wire is determined my the current draw of the lights. The standard size for lighting in many TT's is 14 gage with a 15 amp fuse.
Tapping into an existing circuit means the wire gage you use must match the fuse on that circuit. Find the fuse. A 15 amp fuse means 14 gage wire. A 20 amp fuse would mean 12 gage wire.
You can use smaller wire sized to match the current draw of the light. You must put a fuse in the smaller wire to match its ampacity.
Sorry I don't have a wiring chart for 12 volts available. You can find one using a google search. May be someone else knows the small size ampacities.
