My only lights are knogs. Decent but not fucking crazy £ lights that will actually give some night visibility sans streetlights?

There's a lights thread here: http://www.lfgss.com/thread10329-55.html#post3804691

There are obvs two parts to lights; 1) being seen by others, and 2) you seeing your way.

Decent lights tend to last if they're looked after so it's something that won't be a waste if you invest in a decent one.

That said for the rear I would just go for the cheap chinese ones on ebay. As a driver IME more cheap rear lights are better than less brighter ones. I'd say definitely have at least 2 rears (one constant + 1/2 flashing). If you mount then near or over something reflective then it makes a significant visible difference from a drivers perspective. TBH reflective stuff is always great for drivers.

For the front from a visibility POV I think more cheap ones as still probably better. But if you need something for country roads then you'll want something you can actually see by. I've got a Hope and an old catseye like this:

The Hope is much nicer and brighter, but I can still see my way with the old Cateye so I reckon something like this would probably be fine as well.
The lights thread should give you a pretty good answer though.
