Bike rear lights Black Friday: USB, dynamo deals

USB, battery, dynamo or electric bike battery

The USB rechargeable light attaches to the seat post, a stay or a bag and can be moved from one bike to another. The dynamo light, screwed onto the mudguard or rack, turns on as soon as the wheel spins, without a battery to keep an eye on. On an electric bike, a light designed to connect to its battery turns on with the system, without needing a separate charge. For a rack light, check the spacing of the fixing screws: it must match that of your rack.

The rule, then the comparison of discounts

According to service-public.gouv.fr, the mandatory rear position light is red and non-flashing, at night or during the day in low visibility, and must remain clearly visible from the back; a trailer receives the same equipment. A non-flashing stop light and a second fixed rear light, which the cyclist can carry on them, are allowed in addition. Before comparing two strikethrough prices, make sure they are for the same light: same voltage for a model connected to an electric bike, same fixings provided, same charging connector, same waterproof rating. A discounted light sold without its rack mount cannot be compared to a complete light.

Brands of rear lights from the operation

Herrmans, a Finnish manufacturer of bike components, offers the H-Trace for racks, for dynamo or electric bike, as well as the Goggle Xi with battery, which lights up with motion.

Spanninga, a family-owned business from Joure, Netherlands, covers the mudguard with the Pixeo and the NR9, the rack with the Duxo or the Safe, the latter offered with a stop light option.

NiteRider offers the Sentinel 250, whose Laser Lane modes project two lines onto the ground that create a corridor around the cyclist.

Cateye integrates an accelerometer into the Sync Kinetic: the light intensifies when the bike slows down, like a stop light.

Knog, an Australian brand that originated the Frog, the first silicone bike light, adds here the Plus and the Blinder Link, which attaches to the rack.

The other lights from the operation

To see the road and not just be seen, add a headlight from the front lights of the Black Friday, or choose directly a front and rear set. The page Black Friday bike lights gathers all the offers, and the complete guide remains on the bike lighting page, open all year round. After the operation, clearance lights go to clearance and the latest models join the new arrivals.

Frequently asked questions

Can you ride at night with a flashing rear light?

Not to meet the requirement: the position light required in darkness is a non-flashing red light. As night falls, switch your light to fixed mode.

What is the purpose of a stop light on a bike?

It signals slowing to those behind. Automatic models, like the Sync Kinetic from Cateye, detect deceleration and increase their intensity. This light is optional and adds to the position light.

How long does a rear light battery last?

It all depends on the mode: the Sync Kinetic from Cateye claims 15 hours in strong mode and 50 hours in low mode. Compare the runtimes in the fixed mode you will use at night.

Do you have to wait until Friday to find a discounted rear light?

Not necessarily. This Friday after Thanksgiving marks the peak of the operation, but Vélo-Store maintains its Black Friday discounts on rear lights throughout the entire month. Wherever you attach it, choose a location that is not obscured by any bag.

Does the rear reflector replace the light?

No. The red reflector is required at all times, but it only reflects the light from the headlights that shine on it. At night, the position light remains mandatory in addition.
