I've been thinking and shopping for some lights for the trailer.
LED lighting is expensive!!
Then I had a lighting brainstorm. (Sorry if this has already been posted...)
I picked up a package of those cheap LED Flashlights that are everywhere for two or three bucks.
There were five in a blister pack for $9.00
Cheapo Flashlight
The end with the switch un-screws, there's a battery holder inside.
I cut the barrel off, near the light end.
Soldered some wires... (Note, on the switch, to keep from melting it, I wrapped the wire around the threads tightly
and soldered the wire where I twisted it. Some epoxy or hot glue and this connection will be fine.)
In your foam, drill 7/8th holes for the light and the switch.
Make the depth the same as the depth of the light and switch.
The lights and switches can be anywhere.
Cut a V in the foam to run the wires between the battery pack, switch and light(s).
A couple dabs of hot glue to hold the wires then spackling compound over the grooves.
The finished product
A trailer full of flush mount lights for ten bucks and a little wire.
I don't know if I'll put 12V wiring inside at all. (Yet anyway)
These lights use 3 triple A batteries. I will wire them all to three D cells velcro'd in the closet.
The batteries will probably last the whole season.
Enjoy
