I have always had a great experience with Olight's flashlights due to their magnetic charging, long battery life, bright LED, and durability. I purchased this light to put on my beach cruiser and I have to say I am very impressed.BRIGHTNESS:The light very bright and does a fantastic job of illuminating the path in front of you. It is also bright enough to catch the eyes of oncoming cars. A good 400 lumens with adjustable brightness settings and also a blinking mode. The lens of the light is half textured with the top half being a blurry texture and the bottom half being clear. the reasoning behind this is so it doesn't completely blind people coming towards you but will still do a good job of illuminating your path. In my opinion, it doesnt really made a difference, people are still getting blinded by the light when coming towards me. I actually had a pedestrian trying to shield their eyes while walking past me even with the light on the lowest setting.BATTERY LIFE:The battery life is great! On the lowest setting (which is still very bright) I can get hours on a single charge. Its also nice to have a rechargeable battery instead of going though a bunch of disposable batteries. One downside (if you even consider this a downside) is that this light doesn't have the magnetic charging ability that Olight is known for. It uses a USB Cable to charge. Olight doesnt supply a power block to plug into the outlet either, so your going to have to plug the cable into your computer or an existing charging block if you have one.MOUNTING:The mounting bracket is great. it is sturdy and will fit on most handlebars. It has a quick detach which will remove the light from the bracket if you simply rotate the light 90 degrees. This makes it very quick and easy to pop the light off to charge it and simply pop it back on after its fully charged.OTHER THOUGHTS:Something that I love having in all my lights is a battery indicator. This light has one. the power button will illuminate when the light is on and will either be green, yellow, or red depending on the battery life.A fantastic light that is well worth the money. Very good quality. Just dont lose the charging cable. ### ⭐⭐⭐⭐⭐ Great value and easy to use *by on Reviewed in the United States November 29, 2023* TLDR: I'm very happy with it. I like the Garmin mount. And it's easy to use.I've purchased a number of inexpensive bike lights over for years. I'd find an inexpensive one and over the next year it would eventually die. The battery would go bad or something in the mount system would break. I'd find another one and wash/rinse/repeat. I commute by bike to work most weeks of the year in the midwest and we get some cold weather and can hit some extremes in both directions.OK. Fine. I was buying cheap, crappy lights because I didn't want to spend the $$. And yet I paid more over the years because I was a tight*** fool.This light is solid and the button is easy to use even with gloves on. I like the Garmin mount. I do wish I could adjust the light position left-right insead of up/down but that's a minor issue.I tried a number of different USB-C cables (A-C and C-C) and they all charged the light. I haven't been able to really test the length of charge since my rides to work are less than 2 hrs each way. The rubber cover for the charging port covers it very well and seems sturdy.It's bright enough for me since I ride on paved trails and roads. If you you aren't sure if this will be bright enough then you probably want to get the next level up.I'm happy I decided to spend a little more $$ and get a better light. I think this one is worth it and the light and mount system build feel sturdy enough to last much longer than my previous lights. ### ⭐⭐⭐⭐⭐ Best bike light on the planet! *by on Reviewed in the United States February 24, 2026* I wish I would have come across this before.I was looking for a bike light that met three absolute requirements.1) Good with winter gloves (most important)2) require very little width space on handlebars3) not require having to go though all modes to simply turn on and off4) water-proof and not just resistantThis light meets and exceeds all of these. I can operate it very well with thick ski mittens and glove liners underneath them. This should be so on all bike lights. Why should you want ( in sub-zero weather) to have to stop your bike and take off your gloves just to turn on or off or change modes on a head lamp? After doing that my fingers are usually so cold I just want to go back home.This light easily fit the location on handlebars that I needed.Turning on and off only requires a press of the button. And when turned on it automatically goes back to the mode it was turned off in.It's IP7 waterproofLike all other Olight products I've owned this is very well made and simply does what is required. ## Frequently Bought Together - OLIGHT RN 400 LED Bike Lights, 400 Lumens USB Type-C Rechargeable Front Light, IPX7 Waterproof Bicycle Headlight for Road Urban Cyclists Black - OLIGHT RN 120 C Bike Lights, 120 Lumens Tail Light 260 Degree Visibility, 1500m Viewable Range, USB Rechargeable Bike Break Light, IPX6 Waterproof, Road and Urban Cyclists - OLIGHT Seemee 30 C Bike Light 30 Lumens Tail Light 230 Degree Visibility, 800m Viewable Range, USB Rechargeable Bike Break Light, IPX6 Waterproof, Road and Urban Cyclists --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/250216662-rn-400-led-bike-lights-400-lumens-usb-type-c](https://www.desertcart.tn/products/250216662-rn-400-led-bike-lights-400-lumens-usb-type-c) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-31*
