Barring the installation of the DC circuit breaker panel<\/a> that I mentioned before, I went about installing the first 12 volt DC light that would be powered by the house batteries. \u00a0The need for this was displayed on a short day-trip we took to help a friend clean out her old family’s house, and the boy was unable to read, and I had some trouble finishing loading and packing the bus because the lights that I had installed were AC, and I hadn’t enough cable to run electric power from the house we were cleaning. \u00a0I wasn’t going to just leave the key in the accessory position for the interior lights, because I’m a bit touchy now about running the bus batteries down after our Evangola trip<\/a>.<\/p>\n

Anyhow, I had found two of these lights at Buffalo Reuse<\/a>, though only one of them had its glass globe, and they both had the original 1920-30’s fabric-coated wiring. \u00a0Toward that end, I disassembled the fixture, replaced the old wiring with 14-gauge plastic-coated wire, and installed a new light bulb socket. \u00a0(A tip to people who might want to try rewiring such a fixture – use a ball pull-chain as a wiring snake to get the wire through those support tubes.) \u00a0In retrospect, I probably could have used 18 gauge wire, but I tend toward overbuilding anyhow.<\/p>\n

Unfortunately, the ‘cup’ that holds the globe was lightly cracked and I haven’t been able to find a replacement, as it’s smaller than standard. \u00a0It’s a usual thing for such lamps, however, as the older brass gets brittle. \u00a0I decided that it would be okay, though, as I was going to cushion the cup anyhow, so I went about that. \u00a0I used some vinyl electrical tape to circle the interior of the cup, and then to surround the base of the globe as well, as this would keep road vibration from causing any problems. \u00a0I then went about gently scraping all the old paint flecks from the brass and glass.<\/p>\n

However, getting the light refurbished was the easy part. \u00a0I wanted the light to rest above where the table will be in the cabin area of the bus, and the ceiling there is, of course, curved. \u00a0I wanted to have a flat base (parallel to the floor, that is) to mount the light to, and I had the wood to work with, but the curve looked tricky.<\/p>\n

\"The<\/a>As a woodworker, I knew the importance of having a jig or template to help and didn’t want to do the ‘trial and error’ method of creating one, until I realized that I had one already – the rear interior endcap!<\/p>\n

I used some MDF that I had about, and traced the endcap, and cut it out, making sure to draw on plenty of lines at 90 degree angles to the flat base of the endcap. \u00a0These were important, just in case the smaller bit of the template (where the MDF wasn’t wide enough to fit the whole of the endcap might not be exactly parallel to the base) …<\/p>\n

So, armed with the new template, I worked out how far from the window edge the light needed to be and set about making a base that would fit the light AND the ceiling. \u00a0I had some 7\/8″ thick oak to work with and cut it to 5 1\/2″ squares, and traced the curve onto one.<\/p>\n

Careful cutting on the bandsaw, and then shaping with the bench sander yielded a very nice fitting piece of curved oak. \u00a0A 2″ forstner bit cut a smooth access core down through the curved wood, setting the stage for the important attachment bit for the light fixture; the part with the screw fitting on it.<\/p>\n

The ‘light fixture mounting attachment’ needed to be sunk into the wood, parallel to the flat base, and this was quickly undertaken with a wood chisel. \u00a0Since I was working with oak, and going with the grain of the wood, this wasn’t bad at all.<\/p>\n

I put a second piece of oak under the curved one to give a nice solid base for the lamp. \u00a0I did this because the thin edge of the curved piece I had cut was really thin. \u00a0I was afraid that if I just attached the lamp to it, it would crack or pull the attaching screws right through the wood. \u00a0Plus the routing on the bottom would be another nice touch of decoration that would show in the bus.<\/p>\n

Using a countersinking bit I put four #10 screws into the two pieces of oak together, and drilled some holes through to the bottom and countersunk from the bottom for the metal pan-head screws that would attach it to the ceiling. \u00a0I then gave it a coating of stain and let it rest while getting the rest of the job ready.<\/p>\n

Loading a drill just smaller than the metal screws that would affix the wood to the ceiling, I pre-drilled one hole, and marked the center of the access channel in the wooden base. \u00a0I then switched to the hole saw and cut through the metal of the ceiling to so the wires could be run.<\/p>\n

Using a regular wire snake to run the wires, it was a simple thing to get power to the location. \u00a0I ran 12 gauge wire from the converter to where the switch was going to be at the windows, then ran the 14 gauge wire from there, as I planned on hooking more lights in on this same circuit.<\/p>\n

While I’m really looking to run some manner of dimmer in on this circuit, for now, I just put in a pull-switch. \u00a0It was easy to drill a hole in the exposed ceiling sheet metal, and for now the circuit is grounded to the frame.<\/p>\n

After that, it was a simple matter of connecting the wires at the lamp, and tightening the screw pole to cinch it up to the wood.<\/p>\n

In trying to make the batteries last as long as possible, I wanted to have the most efficient lighting that I could, and went for some LED lights. \u00a0Most of the problems with LED lighting seem to be in that the LEDs only put out light in a relatively tight beam, making them tough to use in a standard fixture. \u00a0Toward dealing with this, I found this multi-directional style of bulb, in both 7 and 9 watts:<\/p>\n

I have to say that these are SUPER bright on 12 volts, and while they say that they’re rated up to 24 volts, I don’t think I’d want to see them – they’d be way too bright. \u00a0As it is, the bulb does stick up over the globe a little, but the upward-facing LEDs provide a lot of indirect light off the bus ceiling (and show the places where it really needs to be cleaned!).<\/p>\n

These bulbs are the soft-white version, and the vendor that I got these from indicates that there’s a bright-white version, but these seem very white compared to an incandescent, or even CFL soft-white bulb. \u00a0I did light them up when it got dark as well, and got these results:<\/p>\n
