For a rarely used back up light, I honestly like that feature. One less charger to carry. I'm not a huge fan of batteries with the charger built in, I broke one from a drop falling off the counter.
I'm in a bit of a bind trying to figure out which back up light to replace my CX1s with, as it is becoming apparent that the availability of even used CX1s is drying up.
Trying to find a good replacement. The CX2 is a bit long, but I do have just enough room on my harnesses to make it work. They turn on with a mode that is good for greater than 2 hours runtime, and is good enough to even scooter with. But it lacks a lock.
The DGX 1000-6 is compelling since someone mentioned it has a lock. But I wish I could program it to turn on in medium mode as default, that would give me the runtime I desire without having to remember to turn it down.
