It detects vehicles up to 175 meters back with a 60-degree radar beam, classifies them by size and threat level in real time, and pushes that information to your Edge computer, compatible watch, or the free Varia smartphone app. You know what's coming before you hear it — and you know whether it's a sedan or a truck.\u003c\/p\u003e\n  \u003cp\u003eAt 100 lumens in Day Flash mode, the RearVue 820 is 58% brighter than the light it replaces, visible from over 1.2 miles away. An integrated brake light detects when you're slowing and triggers a rapid-flash pattern automatically — no button press, no thought required. Four light modes cover every scenario: Day Flash for maximum daytime visibility, Night Flash at 40 lumens for after-dark rides, Solid at 25 lumens for steady output, and Peloton at 8 lumens when you're drafting and need radar without blinding the wheel behind you.\u003c\/p\u003e\n  \u003cp\u003eBattery life runs up to 24 hours in Day Flash and 30 hours in radar-only mode — enough for a full week of commuting or a 200-mile gran fondo without touching the charger.

It also works with Wahoo, Hammerhead, and Stages head units for standard radar alerts, and with Garmin watches for on-wrist notifications. At 90 grams with an IPX7 water rating, it mounts to round, aero, and D-shaped seatposts with a quarter-turn mechanism that locks on and releases in seconds.\u003c\/p\u003e\n  \u003ch3\u003eGarmin Varia RearVue 820 Highlights\u003c\/h3\u003e\n  \u003cul class=\"specs_at_a_glance\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRadar Range:\u003c\/strong\u003e 175 meters with a 60-degree beam width — 35 meters farther than the RTL515.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVisibility:\u003c\/strong\u003e 100 lumens in Day Flash, visible from 1.24 miles (2 km).\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVehicle Intelligence:\u003c\/strong\u003e Classifies vehicles by size (small, medium, large) and threat level based on speed, trajectory, and lateral position.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAutomatic Brake Light:\u003c\/strong\u003e Accelerometer detects deceleration and triggers a rapid-flash braking pattern — no input required.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBattery Life:\u003c\/strong\u003e Up to 24 hours (Day Flash), 15 hours (Peloton), 30 hours (radar-only).
