New firefly lights go great with my new helmet on my recumbent racing cycle

It’s so much fun to ride up the night now. The lights work synchronized. With the helmet lights and also potentially with other riders. There is a wireless application for your smart phone that makes everything work together beautifully. It’s a little bit different, I wouldn’t say complex because it’s simple. It’s just something that requires a little bit of read the instructions before you try to do it type thing lol. The way it’s a super bright. The helmet is very reliable and I’ve got the big firefly lights the mini light attached to my whip antenna, integrated turn signals and it all flashes like a Christmas tree on the Fourth of July!. I had somebody tell me how far away they could see me coming and that made me very happy because I raced my wheelchairs and people just aren’t looking for a guy by himself racing his wheelchair up and down the street maximum visibility is the key. The battery life on the helmet is excellent and there are many different flash patterns that cover everything from a basic headlight for night riding to a daytime flash attention getting light. The firefly lights are very versatile and there are amazingly reasonably priced. Each light is $50 but considering they can operate interchangeably as a headlight side light tail light or turn signal I think they’re wonderfully inventive., and such great safe fun! I had people stop me on the street and ask where they could get one of the helmets. And I come back and grab the fireflies that I’ve got matched up with it and that creates even more excitement. I’ve got the whole outfit matched up with my action camera set for extra fun. I also have a real bright auxiliary helmet light that is attached to my new ultra helmet with in Action camera mount. This used to be my primary light, but the battery runs down too fast so the combination is a lot of fun and I can always take the white off the outside of the helmet and interchange it with a GoPro action camera. If I’ve seen this helmet before I bought the exterior lights I probably would’ve just stuck with the Lumos products. That all around I have no regrets. I almost got ran over by a bus before I put these lights on my recumbent cycle. I lay on my back and operate that thing with my arms and my backside is about 6 inches off the ground even when I’m in the bike lane people are not looking for something that looks like an oversize roller-skate With a person laying on the back LMAO . It almost looks like a runway stretcher! I’ll take some pictures of all the way it’s working together with the helmet on my recumbent. The accessory turn signal switch that’s available at a modest extra price is worth the money because it helps integrate all the lights together with the helmet and as a bonus, it has a sensor That activates a brake light for you. The turn signals even make a tone to remind you to turn them off after you make your turn. I am a space systems integration engineer by trade and this is some exceptional engineering, especially for a consumer products! Keep up the good work! I will keep adding to my collection with my next check. Shine light everybody you’ll never regret it.
