Lights

Finaly decided its too dangous to keep using a cateye for my rear light (TL-LD600)
I'm on my 2nd one and they seem to suffer from vibration battery death
Unless you stop and give them a good bang - they are either at halfpower or dead completely

Looking to replace it with either a RSP Night Flare or X-Light
Can anyone recommend either?

It seems that you have a certain preference for a light that looks and is shaped just like Cateye TL-LD600. Certainly The RSP Night Flare and the X-Light look to be nearly exact copies. But for brightness, there is none more powerful of its type, than the BLT Fantom XR9. For a lower price alternative, there is the truly excellent RSP Astrum Rear.
