I ordered the scooter combo pack for my girlfriend's bike and her scooter so she can switch them out easily going back and forth to work that is a pretty cool feature that covers both vehicles no problem super easy to switch out and quick for her depending on which thing she wants to take that day. She already had a headlight and taillight she just wasn't visible enough on the busy streets around here and these things definitely do the trick. I also bought the combo headlight pack or my meepo Mini 2 and these things definitely make me feel safer when it starts getting a little darker and you're still out then holding a flashlight in one hand which is what I used to do it's great when I'm out taking the dog for a walk and it gets a little dark I can still see every crack and rock in the road in front of me flying along at 15 miles per hour. Originally I did not purchase the tail lights for my electric longboard and I just have a helmet that flashes but I actually turned around a couple days ago and ordered the taillights too I wish I had gotten this 10% off to make a review earlier because now I've literally bought every product from you guys on for every vehicle I have so I don't really know what better recommendation I can give for that and I don't really know what I'll use it on in the future if you guys just want to figure out a way to hook me up some other way that's fine you guys make a great product. No I'm just hoping they're nice and durable and the batteries last for years to come because out the box I think you guys have the competition beat it's definitely worth the extra couple bucks to get quality and not just replace the damn things every time you crash or they get a little wet or the batteries go to crap. oh yeah don't stare into them directly when you turn them on they are brighter then Gods a****** and you won't be able to see you for the first 5 minutes of your ride LOL.
