installing Tomar Industries Adlake Marker Lights

Ward HOGR Forum Member SUPPORTING MEMBERDIGITAL SUBSCRIBER

I'm using GRJs LED 12V lighting board to power LED lighting for my MTH RK Madison cars.

I'm also installing Tomar Industries Adlake Marker Lights in the observation car.

Instead of powering the marker lights with track voltage and using the voltage regulator & resisters that came with the marker light kit, I was thinking of wiring the marker 3V LEDs into GRJs 12v lighting board and using something like 470 ohm resister which should supply the LEDs with 20mA.

My thinking is that GRJs lighting board already has the circuitry to hold constant voltage and prevent flickering.

Comments?

Thanks

I will wait for GRJ's response.

@Ward H I'm pretty sure I know the answer, but I'll leave that to John. He likely hasn't seen your question. This should get his attention:

I'd be using more like a 1K to 2K resistor, I think you'll find that the 470 makes the markers look more like headlights. For the three marker/tail lights on many observation cars, I put them all in series and use a 1K resistor in the string to light them all. That whole string just gets soldered to one of the many sets of pads on the lighting strip, that's always one close to the markers.
