Steve - I bought some from China with those functions almost a decade ago.Bought 3 iirc. helmet brake light | eBay
Fitted them - ran with them. Made the helmet rattle.
Gave them away to a fried whose girlfriend rides in traffic alot.
3oz is 85 grams - I would spend money to shave that weight off my lid.
