more Xmas Leds lights on the model railroad

And this is at night. I got some 'fairy lights', which are LED's blobs on a pair of wires, and strung them under the eaves of a 40-year old plastic Atlas small town depot

The LED's are normally 3 inches apart, but I cut wires and soldered them so the lights are about an inch apart to match the spacing over doorways and corners of the passenger platform. It's not a professional installation; I just pushed the LED's and wires through the braces of the roof eaves. it's just enough to put the light away and down around the building. Just don't look underneath to see my mess.

The battery pack and controller is just stuffed inside the building. The beauty of these lights is they work even if I don't turn on the railroad power supplies, If I am walking past on my way to somewhere else, the railroad still looks 'busy' even when I don't turn on the room lights. These lights have settings of off, steady on, blink, or fade. And they run on an internal timer, on for 6 hours every time, off for 18 hours, and that repeats everyday like clockwork. It can hold 3 AA batteries, but the light level looks good at just 2 batteries. I use a wire jumper/filler piece to take the place of the 'missing' battery. And even better, this can use batteries that are too dead to run radios and cameras, and they still last for months before needing changing.

Here's another crude light installation, behind a coaling tower.
It has the more typical 3mm LED lamp size, and I was able to leave most of the green Christmas insulation on it.

It's two LED lights strapped to a mast of old building wire that is stuck in a hole in the wood base.

I don't intend to hide it or make it professionally installed,
because most of the time it is hidden from my main view,
it's on the back side of this tower.

I put two lights on it,
aimed different directions to highlight two dark areas in the back corner of the layout

Here's the corner in daylight

here are two areas with my night lights

And I did one last building at the front edge of the layout. Russell's old tower building guards a track junction.

I put in another mast, stuck in a hole in the wood base. I did a half-way installation with this one, the wires are coming through a hole and the battery box is below. When the tower is placed alongside the light, with the LED outside of the walls, all the light power shines this way.

And I can set the tower building over the LED with my messy wiring and hide that. Then I align the building to the light, so most of the light power shines out the back window to brighten that dark spot of the railroad; and some light stays inside, making a pleasant warm glow coming out the windows on the main viewed side
