OLIGHT RN 400 LED Bike Lights, 400 Lumens USB Type-C Rechargeable Front Light, IPX7 Waterproof Bicycle Headlight for Road Urban Cyclists Black

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.

Nice and bright. Holds a charge.

Excellent lights and very bright! Highly recommend

I have always been an fan of Olights tactical flashlights, so when they came out with a bicycle light, I was very interested. 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.

I don’t ride at night. I bought this light to be a daytime running light. It charges quickly and runs forever. I have never gotten a low battery indicator. It’s waterproof. I found myself in the middle of a monsoon during a 50mile ride. It didn’t seem to care. The mount is very solid and low profile. I am a big fan of Olight products. I also have the Olight RN-120 tail light. Great combo. People with expensive “ name brand” road bike lights are always shocked that the Olights are so compact, bright, 1/2 the price, and better than their lights. I have even given one as a gift for a friend. Seriously......these are great lights! You should check out the Olight Baton SR1 flashlights also.

OLIGHT makes great lights. There is a ton to like. Standard Garmin/Wahoo mounting system, USB-C charging, lots of light functions, including a nice daylight flash mode. They have been waterproof enough to survive rain and durable enough to survive drops. I very much recommend the brand and these lights in the larger battery capacity. This smaller light, however, runs out of power after about 4 hours, even in blink mode. I haven't even tried to run it as a light at night because I don't think it would last more than an hour. Maybe it would be OK as a backup or if you do fairly short rides/commutes with it. It certainly is lighter than their bigger models. If you are looking for a great light, look at the 900 and 1200+ models of this light.

OH MY GOODNESS. I was just going to leave a 1 star review, i bought this light 30 days ago and thought it was broke , it would say it was charged then would not turn on and show red . I have lots of olight products and was completely disappointed until I held the button down for like 5 seconds then bam the freaking light turns on . There’s all kinds of bad reviews about it not working, the reality it we need to read the instructions. It HAS A LOCK MODE . thanks olight!!!

The light stopped working within a month. It will not maintain a charge. The product allegedly comes with a three year warranty. I submitted a warranty claim on the Olight website. Olight informed me that they could not replace the product because the product is currently out of stock on their site. Olight then offered me a store credit for their site. Olight does not sell any bicycle lights on their website. Thus, a store credit does not resolve my issue. Olight refuses to refund me, repair the light, or send me a new a light. The light is broken within a month of normal use and the warranty is a sham.
