BLITZU Ultra Bright USB-C Rechargeable Bike Light Set - 1200 Lumen Waterproof Bicycle Headlight & Taillight Combo for Night Riding - Easy Install Cycling Safety Lights for Road/Mountain Bikes - Perfect for Commuting, Trail Adventures & Family Cycling

I purchased a month or so ago this bike light combo and I could not be happier. Accidentally, I purchased two of them and intended to send one back. However, since I like it so much I will keep them both. The headlight is small, yet powerful, and seems to last many hours (I commute to work about 1 hr daily, and charge lights during the weekend, never had a problem). The front light has three intensity settings and one blinking mode, which uses the highest intensity of the light and seems to be visible several blocks ahead (based on the street signs reflecting back). The rear light is small, light and versatile and also works many hours. I use often the Blitzu rear light at night and is very visible, no problems. For daylight rear lighting, however, I use either a Cateye X2 (or X3) or a Cygolite Hotshot 100 which are stronger and thus more visible. Both Blitzu lights are USB rechargeable, which is a big plus. Both lights are easy to put on and take off the bike, there are elastic bands used for installation. I even purchased extra rubber bands to have some spares, in case I need. I highly recommend themAlso, some quick extra info on my experience with the various bike lights I own, including Blitzu, INTEY, Cygolite and Cateye.I have several bikes and several headlights (and taillights)I did a few day and night tests, to check how visible my bike lights are from a moving car. One important observation: there is no need, in my opinion, of a bike light brighter than 1000-1200 lumens. On high, such a light can bother the oncoming traffic. To give you an example: in the past, while I was using more regularly an older 1000 lumen flashlight in strobe mode on the bike, there were on several occasions cars bringing to my attention that my light was bothering them. Currently, I like using an INTEY 1000 light, on pulse mode (not flashing/strobe), which I find perfect for night riding (not blinding yet very visible) and works during the day also, if you want to. However, for daylighting I prefer stronger pulse-lights. To do this, I have three options: either use the INTEY in strobe-mode, which is VERY bright. Or, I also have a Cygolite Metro Pro 1100 and a Cygolite Dash 600. Both of them are very good for daylighting when using the main LED. My Cateye Volt 1200 in flashing mode is also great for daylight. However, at night, all these stronger lights I think will bother the traffic too much. Therefore, I prefer to combine the INTEY steady/pulse light with flashing from a second bike headlight. For this, I either use the flashing 4 LEDs of the Dash 600 or I use the flashing mode of this BLITZU Gator 390 light. This combination works very well for me. Both of these flashing lights attract attention, yet are not blinding. I think a combination of TWO Blitzu headlights, on set on constant and the other flashing would do the same job. Certainly, when I ride in heavy traffic (particularly during daytime), I prefer the more rapid flashing mode of stronger lights, such as the Volt 1200, or Metro Pro 1100 or the strobe mode of the INTEY 1000. They are all VERY visible and keep me safe.
