6 reasons to buy

NiteRider’s Pro 4200 meets the ANSI FL1 standard, which includes a test that drops the light onto concrete from one meter.
Owners say installing the mount and attaching the light and battery pack is straightforward.
A tester and owners appreciate the thumb remote for operating the light from the bars.
Buyers and experts praise the brightness at full power.
The battery pack has a USB port to charge other devices.
Additional battery packs can be purchased separately to use as spares during rides.

6 reasons not to buy

NiteRider claims battery life is 1.5 hours at full brightness, but testers get just over an hour.
The battery is very bulky and NiteRider’s suggested mounting position on the top tube may obstruct pedaling. A reviewer opts to strap it to the bottle cage, instead.
An expert feels the beam’s harsh cut-off makes the light unsuitable for night riding on technical trails with sharp turns.
The Pro 4200’s water resistance rating of IP64 is below average and may not be sufficient for riding in heavy rain.
The cables for the thumb remote are short, so it may be difficult to reach the button on handlebars 720mm or wider, according to a tester.
The Pro 4200 is very expensive.

Bottom line

The NiteRider Pro 4200 Enduro Remote is a rechargeable handlebar-mounted light that fits handlebars up to 35mm in diameter. It has seven modes, including two flashing, ranging from 600lm to 4200lm. Reviewers praise the brightness, solid construction, easy installation, and convenient thumb remote. However, tests show the battery life at max brightness falls short of NiteRider's claims. Additionally, the battery pack is very bulky and may obstruct pedaling if installed as recommended, and the harsh beam cut-off is deemed unsuitable for technical trail riding. While owners are mostly pleased with the Pro 4200, experts feel it falls short of NiteRider's promise.

Level 5 expert

Despite the Pro 4200 Enduro’s promise of high output, a big battery, and easy-to-use functionality, I was disappointed with the beam’s spread given NiteRider’s claims.

NiteRider Pro 4200 Enduro Light Review

Level 5 expert

The NiteRider Pro 4200 Enduro puts out a massive amount of light and we could see for miles. Unfortunately, there’s a real hard edge to the bottom of the beam, and on full whack, the [battery life] really suffers – it lasted just over an hour.
