At 40 lumens with four output modes — steady high, steady low, fast flash, and pulse flash — it covers everything from low-light commutes to full dark training rides, with battery life ranging from 7 hours on fast flash up to 36 hours on steady low.\u003c\/p\u003e\n\n\u003cp\u003eTwo separate buttons give you independent control over the taillight and the laser lane, so you can run either or both depending on conditions. The laser lane itself offers three modes — steady, fast flash, and slow flash. There's also a group ride mode that pulses the taillight in a way that's easier on riders drafting behind you. A built-in \u003cstrong\u003ebattery indicator\u003c\/strong\u003e flashes blue when charge is above 25% and red when it's running low, so you're never caught out mid-ride without warning.\u003c\/p\u003e\n\n\u003ch3\u003eNiterider Sentinel 40 Rear Light Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eOutput: 40 lumens\u003c\/li\u003e\n  \u003cli\u003eTaillight modes: Steady high, steady low, fast flash, pulse flash, group ride\u003c\/li\u003e\n  \u003cli\u003eLaser lane modes: Steady, fast flash, slow flash\u003c\/li\u003e\n  \u003cli\u003eBattery life: Up to 7 hours (fast flash) — up to 36 hours (steady low)\u003c\/li\u003e\n  \u003cli\u003eBattery indicator: Blue (above 25%) \/ Red (low charge)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Niterider","offers":[{"title":"Default Title","offer_id":43705664241708,"sku":"5076","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/niterider-sentinel-40-rear-light-6745719.jpg?v=1771299625","url":"https:\/\/ricycles.com\/products\/niterider-sentinel-40-rear-light","provider":"RA Cycles","version":"1.0","type":"link"}
