I keep buying strings of colored LEDs for the belt line. They seem to last about 9 months or so. I'm thinking of a different system - but for now, I installed another string to replace the last one that blew out.
And this time, thanks to Brian/Moosetags - I attempted a connection to the battery (well, I haven't done it on the trailer yet...).
I got one of these:
And one of these:
Now I hadn't really thought of it until I got the parts and started playing around with it and I'd buy different parts perhaps because I ended up cutting the female end off both pieces. I soldered about 10' of cable with the male end to the pin adapter out of the light strip (that goes to a "brick" for 110v). Since that male end has a fuse in it already, I realized I didn't need a fuse for the female end coming off the battery, so I eliminated that fuse and soldered the female end I cut off the one cord on to the eyelet adapters for the battery connection. Oh - and I used a volt meter to triple check to be sure all 3 components I was working with interpreted "red" as "positive".
So the LED strip will terminate in a male cigarette lighter adapter that I can plug in to the female adapter permanently connected to the battery.
I tested it out at home by plugging the male adapter in to my truck's cigarette lighter and powered up yet another spare string of LEDs and it worked perfectly!
So thank you, Brian! Great tip and it worked perfectly!
