The other night, I was browsing th posts on this forum and came across a place where someone had installed a 1.5volt LED headlight in a JWBowker 2-4-0. Since I can't find the post again, I thought I would start a new topic to see if anybody could tell me how this is done. I would like to add headlights to some of my engines, a pair of 'Bowkers among them.
Thanks to anybody who can help

| I'll second that StringBob. I'd like to see a photo story on adding a headlight.

The clear water LED's are a bright White color, I use these for diesels/electrics.
For Locomotive's use the Warm White LED's, which are more of a yellow color. For my Athearn engines I use the 2mm LED's. One must also use a resistor- I get mine form Radio Shack- 470 Ohm 1/4 Watt. One lead goes to a ground, the other goes to a (+) power terminal. You can set the LED behind the plastic lense and it will work fine. For the diesels the LED is the headliight lense. I use a 2mm drill to ream out the hole for the headlight/LED.
I get the LED's on Ebay from Dmmwem, he has a store and a wide range of LED's.

Thanks, AF Kid. I'm going to find some of those warm white LED's. I assume they are 1.5 volt, correct?

My hobby shop in Virginia started selling LED lights for locos, from bright whites to warm whites. What's neat about them is that they have integral resistor and diode pack, AND work in either forward or reverse mode. Can get them in 1, 1.5, 3, 5 mm sizes. About $4 each. I'm going to buy some for myself,and I'll post them on here when I do. I forget the name, but they come in blister packs of 5. Just wire them up and you're good to go.

Bob, it wasn't an LED, it was a super-mini 1.5v bulb from Miniatronics. You can see it in this thread. You would need a small surface mount LED in this situation, and most warm white LED's aren't warm enough or are just plain off. The 1.5v bulb even looks a bit like an oil lamp inside.

This is an earlier Bowker with the tender drive, and installing it was a PITA, to be honest, especially routing the wires to keeping them out of the gearing. I used a length of clear plastic tubing (known as spaghetti in the electronics world) as a conduit and glued it to the underside of the boiler weight to one side. There's very little clearance between the weight and the frame. The wires come from the tender where the constant lighting circuit is located.
In the loco, the wires come up through the smokebox and out through a hole drilled into the recess for the location tab on the headlight bracket, then up through a hole drilled in melted plastic that secures headlamp to the bracket, and up inside the lantern. I gave the lantern interior quite a few coats of engine black, and then multiple coats of silver to block light leakage. The reflector is a piece of chrome mylar confetti.

They have to be higher than 1.5v as the Ho transformers are 18v. I use the 2mm ones.

Here's those LEDs I mentioned earlier in the post. These already come with resistors AND rectifiers built in, so you can use them for directional lighting. I don't think you can bypass the directional, so these are better for diesels I suppose. Anyway, the info is in the pictures, you can check out their website and find them. They're roughly $4 apiece, but like I said, they come with the resistor and rectifier already built into the harness. I installed a pair of normal whites into a Conrail diesel, and it looked great. I haven't seen all the color variations in person, so I can't tell you how "warm", blue white, etc. looks. But these are handy if you just want to wire in and go. And they come in size 1.8mm, 2, 3, 5, and maybe others.
