oscillating headlight LED circuit

[Capt.Brigg]

I am looking for a circuit and instructions for wiring an LED ocillating headlight and cab top warning light. I'm sure there must be a chip that will "strobe" an LED to simulate the actual movement of an engine headlight. Any suggestions are greatly appreciated.

If your running DCC that is a programming function in most decoders.

 There used to be a company who made all sorts of circuits like that - constant lighting for DC power, various flashers, etc. For the life of me I cannot think of the name, or if they are even still around. I do remember installing one for a fellow club member back when I belonged to the L&KV. At that time, we had 2 DC walkarounds, one was the MRC CM20, the other was a CMR Hogger. The circuit could, as a constant lighting feature, work off the pulses of pulse power even when they weren;t high enough to actually get the loco moving - this worked great on one pack but not the other (I forget which was which). So on one main, the loco would sit there and flash the beacon so long as the block toggle was on, on the other main, it would only work if the loco was moving.

Richmond Controls.  Jim Hinds makes all kind of circuits.  They work on DC and DCC.

Thank you all for your suggestions. I am running NCE DCC and will search JMRI to see if I can find a headlight CV programming function to simulate oscillation of the LEDs. IF you know which CVs control the forward headlight, that would be helpful.

 Not who I was thinking of, but Richmond Controls has many of the same things and I'm sure you can find what you need there.

Circuitron may still have the flashers/Mars/strobes, etc. available? Website hasn't been updated since 2013!

I recently bought an E.O.T. flasher to use in a trackside signal application.

Good Luck, Ed

NGineering has many circuits too.

I’m not an NCE guy but here are the instructions from my MRC Prodigy

 

 

 

 

 

Hope this helps.

 Stuff liek that is decoder-dependent, not system dependent. SO if you use an NCE decoder, you use the CV vaues the NCE decoder manual lists, regardless of the fact that you use an MRC DCC system.

Hello all,

I have both these effects on my HO scale rotary snow plow along with front and rear headlights that can accommodate Rule 17 lighting.

To achieve these effects I used red 3mm LEDs powered by a TCS KAM4-LED (#1479).

By using this decoder no resistors are necessary when using LEDs.

Because this is a four-function decoder front and rear lights are fully supported along with two other lighting functions.

I assigned lighting functions 3 and 4 to drive the red LEDs. The "forward" LED function is set to "strobe" while the "rear" is set to Gyralite.

With this decoder you could also wire functions 3 and 4 to ditch lights.

Hope this helps.
