Light works great! Ignoring the light for too long... not so much. It started to flicker and I thought about getting gas. Wife texted me and asked me why I wasn't getting the kid from daycare. So I headed home asap. I thought I had enough to get home but it started to sputter and I was in the countryside and away from a gas station, I managed to make it to the nearest gas station but if it had been a few more feet I think I would have been pushing it. Luckily the last 1/2 mile was downhill.
They didn't have a reserve on EFI bikes because they assume if you don't pay attention to the light it's your own damn fault.
