Rear light reccomendations please

[SquareDaff]

I bought a RSM Astrum [2x 1/2 watt] rear light which is very bright and runs for a good 80hrs you can pick them up for about £13 shopping around.

+1 for this. I have 2 mounted horizontally.

I've got the CatEye TL-LD1000.
I like it because it has two strips of LEDs, so you can have one on solid and one on flashing in the same unit, and it's visible from the side too. Build quality is good; I've had mine for 2 years without issues.

It's probably bulkier than some of the other recommendations though.

Smart and Cateye rear lights have always let me down in the rain

I've gone through 2x TL-LD610's since October - they are NOT waterproof.

They are great lights when they work, but take them out in the rain and they mist up inside, start to turn themselves on and off, not let you turn them on and off, then eventually stop working altogether.

Mine were a gift and their customer service didn't want to know as I didn't have a receipt.

Very poor, not recommended.
