Description / 5mm Round Top Pure Green Fast Flashing 2Hz LED - Super Bright
The 5mm Pure Green Fast Flashing 2Hz LED blinks twice per second — a rapid, attention-demanding pulse noticeably faster than the standard 1Hz blink. No 555 timer, no oscillator, no microcontroller required — just apply DC power through a current-limiting resistor and it starts immediately.
| Size | 5mm (T-1 3/4) |
| Effect | ~2Hz (120 flashes/min) |
| Forward Voltage | 3.0-3.4v |
| Brightness | 10,000-12,000mcd |
| Package | T-1 3/4 through-hole DIP |
| Drive Current | 20mA typical |
Built for
- Bicycle safety lights: DIY rear blinker — LED + resistor + battery holder in a weatherproof enclosure. 2Hz is visible to drivers without being disorienting.
- High-priority panel indicators: When 1Hz is not urgent enough — fault warnings, low-battery alerts, over-temperature signals on project enclosures.
- RC vehicle hazard flashers: Amber 2Hz for scale utility trucks, tow trucks, and construction vehicles.
- Escape room countdown props: “Time is running out” warning — faster than ambient, slower than panic.
- Attention-getting displays: Trade show demos, retail point-of-sale, project fair boards — draws the eye without a full strobe.
Makeshift controller trick: Wire this LED in series with standard LEDs, and the entire string will blink together at 2Hz.
Why this instead of a 555 timer? A 555 blinker needs the IC, two resistors, a capacitor, and a PCB. This LED is one component. You cannot adjust the rate, but if ~2Hz is what you need, this is the simplest path.
Polarity matters — long lead is positive (anode). Add a current-limiting resistor matched to your supply voltage. Drop-in replacement for any standard 5mm LED — same footprint, no circuit changes.
