Bike lights

If cost it not an issue go for anything from Exposure.  As the nights are now getting shorter (not by much I know) but there are some deals floating around.

I've used nightrider lights for several years.  The front have 750lumens going up over 1000lumens.  Absolutely fantastic lights for dark roads .  The rear is one of the best I've seen too

Had these for ages. Almost unbelievably powerful for their small size, I actually wouldn't want anything brighter for risk of blinding drivers. Never notice them weakening in brightness whatsoever, even after hours of sustained use (Decathlon states 9.5 hrs life in flashing mode).
More great things about these lights?
*Unlike Decathlons's cheaper lights, these require a more forceful push to turn on and the result is you don't find them flashing in your bag when you take them out in your pocket or bag in the day for use later at night.
*Being identical both flash or sustain in either red or white light so no need to check which one you are putting on the back or front of bike.
*Unlike Decathlon's cheaper lights they have never 'gone mushy' on me in the sense of not responding correctly to presses (seems to happen within only about a month with the cheaper lights)
*No batteries needed!
*Super lightweight and a very compact lovely fit, connecting onto front of your bar facing outwards instead of clipping over the top, meaning it doesn't look like you have a mini bike computer attached. They are practically unnoticable when fitted.

In the Reviews section there are categories for Front, Rear and Sets.

Nightprovision are shit.

We can probably recommend many better options if we had an idea what type of light you need and what your requirements are.  Nice plug for the brand though, another cheap advert maybe?
