I recently bought a set of DT Moto emergency lights for my pickup and after installing them i found when i went to wire them to my battery the wire was too short. I didn't install the grille lights just the visor. Could i cut wires from the grille set and wire them to extend the visor light wire?
I'm looking online to find out what DT Moto lights are. Ok, I see what they are. I didn't know the brand name. LED lights in general are not high current, so they probably use lamp cord. I want to explain something to you about polarity. Electronic circuits are sensitive to the polarity of the DC electricity. The positive (+) and the negative (-) connections must be observed. So many people have absolutely no clue about this. There are just two wires. But if you extend them, you have a 50-50 chance of wiring correctly or incorrectly. There is only one allowable way. If wrong, it WON'T work, and probably will blow up the circuitry. So connection to battery or cigarette lighter plug is extremely important not to reverse the polarity. If just the LED lights got reversed, they wouldn't light, but they wouldn't be injured. Just reverse the wiring. But to the 12 volt source, polarity can't be wrong. Not for an instant. If you look closely at the insulation, you will see that one wire has smooth insulation, and one wire either has milti-ribbed insulation, or a single rib down the side. If you extend wiring, make sure to connect smooth to smooth and ribbed to ribbed. Wires should be soldered with electronic solder and the joints covered with heat shrink tubing. No crimped barrel connectors, or twisted bare wires with tape, or house wiring wire nuts. These methods all beg for failure. I don't know about robbing wire from one place and connecting to another. Is the one wire actually too long? You'll never need it? I guess you could take it. But me personally, I'd go get some wire from a lamp store. Match the wire conductor gauge (size), not the insulation size. Most lamp cord is 18 gauge. Some is 16 gauge. You can get 14 gauge or even 12 gauge. Thicker is a smaller number. Places that install car audio systems often have/sell thicker lamp cord. Have I told you enough?
