Product Details
✓Self-flashing LED with integrated flash circuit - 20 Cool White self-flashing LEDs with built-in flash circuit that pulse on a fixed cadence — suitable for model railroad signals, security indicators, prop electronics, and panel displays with integrated timing
✓Cool white output at 14,000-15,000 mcd - Clear-lens through-hole LED emits cool/clear white light across a 20-30 degree viewing angle at 20mA drive current. Built-in flash IC produces Slow Flashing at 1Hz (one flash per second) from a 12V supply, with flash timing fixed internally.
✓Standard radial through-hole package - Pre-wired DIP body houses the flashing circuit and ships with 15 cm (~6 inch) tinned-end leads ready for soldering or screw-terminal connection. Radial through-hole form factor seats in breadboards, perfboard, and panel-mount holes for clean mounting.
✓Pre-wired flashing construction - Operates directly from a regulated DC source within the 10-15V range, and a built-in current-limiting resistor sets drive current to ~20mA across the input. Animation IC requires steady regulated DC — NOT compatible with DCC track power, AC, or pulsing supplies, which cause erratic flash timing or IC damage.
✓Strobe, beacon, and indicator uses - Cool/clear white 1Hz flash suits emergency-vehicle simulation, attention-getting beacons, security-light effects, novelty strobe props, and panel indicator duty. Self-flashing 14,000-15,000 mcd output stays visible across a 20-30 degree cone for clear signaling.
