Under hood lighting

I used a door pin switch on the ground so the lights come on when I open the hood, and 3M tape to hold wire loom in place and LED strips for the lights. 3M holds up good even in the AZ heat.

 

Normal good practice is to fuse the positive wire but All of those cheap chinese plunger switches switch the negative. That's bad in a vehicle, and unsafe. Think about it.

If there is no fuse between the battery and the positive side of the LED strip what will interrupt the fault current if the led positive gets shorted to negative? You better have comprehensive coverage and a low deductable because your truck is on fire.

The safe way to do this install is to put a fuse between the battery terminal and the LED positive. Put the fuse as close to the battery as possible. Don't worry about the negative leg fuse, it's non-functional. I'd find a way to remove it as it is just adds another failure point.

So, if you are going to switch the negative remember to fuse the positive leg. And also remember the positive side is hot 100% of the time, so if you are working on the light or anything else and accidentally short the positive to ground you'll see some sparks, blow the fuse and have to change your drawers as the result of the surprise...
