Description
The Circuitron 1400 HO Scale DL-1 Oscillating Ditch Lights is a complete ditch-light oscillator driver — produces the alternating left-right flash pattern of modern diesel ditch lights, mandated on North American freight diesels since 1996.
What it does: Drives two LEDs (or two small bulbs) in the prototype ditch-light alternating pattern. Triggered by horn / function output or set to continuous oscillation. Used on every modern Class I road diesel.
- Oscillation: Alternating left / right at prototype rate
- Drives: 2 × LED or 2 × small incandescent (not included)
- Power: 12 V DC (use PS-2 5302 or TP-2 / TP-3)
- Scale fit: HO — circuit sized for typical HO loco shells
- Circuitron SKU: 1400 (Walthers 800-1400)
Tip: Best wired to a DCC sound decoder's auxiliary function output so the ditch lights activate with the horn — exactly as the prototype works.
About Circuitron: A USA-made model-railroad electronics specialist (Maryville, Illinois) founded in the 1970s. Famous for the industry-standard Tortoise slow-motion under-table switch machine and its surface-mount cousin the SMAIL. The full range covers detection (block detectors, Opto-Sensor grade-crossing logic), automation (auto-reversers, external relays, twin-coil alternators), signal / lighting electronics (alternating flashers, ditch-light oscillators, strobe drivers), power supplies, and a complete set of Tortoise / SMAIL replacement parts plus the solderless ZipZ connection system. Most circuits work with AC, DC, or DCC track power unless specifically noted otherwise.
