Brightness and Power

The HJ-040 bike light set delivers a 300 lumen front headlight powered by a built-in 2000 mAh lithium-ion battery. A rear taillight adds a 330 mAh battery. Both units recharge via USB and use a one-touch switch to cycle through four modes: full brightness, half brightness, slow flashing and fast flashing.

Runtime and Weather Limits

Headlight runtime ranges from 5 to 12 hours depending on the mode selected. Taillight runtime spans 9 to 16 hours. The set carries an IPX4 water-resistant rating, so it handles splashing rain but is not submersible. A low-battery indicator on the headlight turns red when power is running low.

Mounting and Daily Use

The headlight clamps to the handlebar with a supplied bracket while the taillight straps to the seat post using a silicone strap with four adjustment openings. Both mounts secure without tools and can be loosened or fastened quickly. The lightweight design suits cycling, hiking, camping or emergency flashlight use.

Questions about this item

Should I choose the 2000 mAh headlight or the 330 mAh taillight version?

The set includes both: the front headlight uses a 2000 mAh battery and the rear taillight uses a 330 mAh battery, so you do not pick between them.

What does the 300 lumen rating mean when I am riding at night?

The headlight produces 300 lumens, giving a bright forward beam with four modes including full and half brightness for seeing the road ahead.

How does the IPX4 rating limit where I can use the lights?

IPX4 means the lights resist splashing water from any direction, so they handle rain and wet roads but are not submersible.
