Should be as simple as it seems using LED's.   I've added headlights, taillights, strobe lights, etc. to small motorized track units, which should be the same as for Streets stuff.  I'm sure Lee has added all kinds of lights to some of his.

 

I like LED's for locomotive headlights as well, they are much more directional than the standard incandescent bulbs and thus look a lot more like real headlights.

a few questions don.

where do you purchase the LEDs and is track power ok or do they need a resister?

You can find thousands of them on eBay. For O scale, you want the 3mm warm white for most headlight applications. The red ones are available in smaller sizes which is great since tail lights are usually smaller than headlights. You'll have to add resistors to run them on 12 volts. This site has information on picking the right resistors for your LED applications. Best bet is to tie the LEDs in series so you only have to use one resistor. White LEDs have a forward voltage of 3-4volts; red, green and yellow are roughly 1.2-1.5volts.

Hope this helps.

best drug night

The rainy street effect in that photo is outstanding.  If I might presume to suggest, a layer of Photoshop falling-rain would make it even more memorable.

 

I took off work today to enjoy working on trains. I just received a NASA K-Line streets vehicle, put it on the track, and one of the headlights was out. I ran it a bit and realized the rear lights work, but only when backing up. Electronics is not my strong suit but...

 

It was a breeze replacing the headlight. I kept looking at the wiring and decided to make a cut and re-splice the rear lights so they are on all the time. It all worked great.

 

The lights are fantastic and it took minutes once I had the courage to snip the wires. I can't wait until this evening to see how it looks at night. I already noticed the lights reflecting off windows in some of the buildings. Terry
