I'm a big fan of Exposure lights - I have a MaXx-D and a joystick. Both are excellent lights, but you'll be paying for that sort of quality and reliability. If I didn't get one of these I'd be most tempted by a Hope, followed by a magicshine for value.
If I had any spare money this year, I might have bought an Exposure six pack.![]()
I like the Exposure designs, because they're essentially cable free, and I have had failures in many cables on other lights, and they can be a faff to route.
The Flash and Flare are good cheap little lights, but relying on unscrewing the lamp unit to turn them on and off is more than a little useless on a £35 light (without batteries!) They work OK for what I carry them for, which is emergency lights for use on group rides, where you can't rely on the other person having a suitable mount, and their rubber band mounting arrangement will work most places.
I just wish Exposure would bring out a decent metal bodied rear light, possibly based on a Joystick, with a red LED, and suitable mounting arrangement.
What worries me about the Six Pack is the weight. ½kg on that mount seems like it's pushing your luck. It's a good mount, although it does tend to wear out and need replacing periodically (otherwise it rattles very annoyingly), but there's a lot of difference between a Joystick and a Six Pack in weight!
