The housing is CNC-machined aluminum, and the optics deliver 270-degree visibility so you're seen from the side as well as directly behind. USB-C charging and a tool-free detach mount mean it's ready to go without much fuss.\u003c\/p\u003e\n\n\u003cp\u003eEight output modes give you a lot of flexibility across conditions. Active Alert mode pushes 250 lumens when the light senses braking; dedicated daytime flash patterns keep you visible in bright conditions; and Femto mode stretches runtime to 60 hours when you just need a background presence on longer, multi-day efforts. The unit is fully waterproof, so output mode is the only adjustment you'll need to make regardless of the weather.\u003c\/p\u003e\n\n\u003ch3\u003eLezyne Saddle Ai Alert 250 Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax output:\u003c\/strong\u003e 250 lumens (Active Alert mode)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput modes:\u003c\/strong\u003e 8 modes, including daytime flash patterns\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax runtime:\u003c\/strong\u003e 60 hours (Femto mode)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVisibility:\u003c\/strong\u003e 270 degrees via wide-angle optics\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e CNC-machined aluminum, waterproof\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCharging:\u003c\/strong\u003e USB-C, tool-free saddle mount\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Lezyne","offers":[{"title":"Default Title","offer_id":43872752304172,"sku":"1-LED-41R-V137","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/lezyne-saddle-ai-alert-250-rear-light-7782007.jpg?v=1771294151","url":"https:\/\/ricycles.com\/products\/lezyne-saddle-ai-alert-250-rear-light","provider":"RA Cycles","version":"1.0","type":"link"}
