Description / 3mm Diffused Flat Top Wide Angle Blue LED - Wide Angle
The 3mm Blue LED (Flat Top Diffused) delivers a wide viewing angle for even illumination from off-axis positions — the right choice when you need guitar pedal indicators (visible from standing height without blinding glare) and panel displays.
The diffused lens softens the wide-angle flat top beam into an even glow with no visible hotspot — trading a small amount of peak brightness for much more uniform light distribution. No visible die point, just a smooth glow across the full lens face.

Why flat top instead of round top?
A standard round-top 3mm LED has a 15–30 degree beam — bright when viewed straight on, but nearly invisible from the side. The flat top (sometimes called a flat head LED or square LED due to its flat lens face) spreads that light wide, making the LED clearly visible whether you are looking down from a standing position, viewing a panel from across a room, or backlighting a translucent surface that needs even coverage with no hotspots.
Common applications
- Automotive gauge cluster backlighting: modern cluster accent, CB radio meter backlight upgrade. The wide beam eliminates the bright-center/dark-edges problem that round-top LEDs cause behind gauge faces. Drop-in for GM Silverado/Sierra, Honda Civic, Jeep Wrangler TJ, Ford Mustang, and Toyota/Lexus clusters.
- Guitar pedal status indicators: Blue is a popular modern alternative to red for custom and boutique pedal builds. The flat top is the standard choice on DIYStompboxes, r/diypedals, and The Gear Page. Diffused lens produces a clean, even glow without a blinding hotspot on a dark stage.
- Arcade pushbutton illumination: Lights up the entire translucent button cap (Sanwa, Seimitsu, Happ/IL) with even color instead of a single bright dot. Also used for marquee backlighting in BYOAC cabinet builds.
- Model railroad building interiors: cool-toned accent for commercial model structures. The wide angle fills HO and N scale structure interiors with realistic lighting instead of a spotlight effect.
- Panel indicators and control boxes: Fits standard 3mm LED holders and panel bezels. The wide angle means the indicator is readable from anywhere in front of the panel, not just dead center.
- Breadboard prototyping: The flat top sits stable in a breadboard hole without rocking, and the wide beam is visible from normal desk-level viewing angles.
3mm flat tops are preferred for smaller guitar pedal enclosures (1590A/1590B), N scale model railroad structures, and compact panel indicators.
Standard T-1 through-hole footprint. Fits all 3mm LED holders, bezels, and panel-mount clips.
