Planet Bike  Spok Light Set

I just needed a flashing light for the rear of the bike at night, so this light fit the bill. I would in no way consider the white front led for lighting. It is more for visibility. The feature that sold me was that it is mounted with a velcro strap. I can take it off when needed, and put back on for night rides. The housing of the LED has a rubber feet so it stays secure on the seat post. The problem I had with other lights is that they use plastic zip ties, as the main component that secures it, that deteriorate rather quickly in the heat that I live around.

i commute via bike to/from work. i wear this on my helmet to make myself a little more noticeable to drivers. it's not a bad light: it gives enough light to pack my bike in the dark conditions but it won't provide you with enough light to help with seeing the road. the issue that i have found is the light stops working in cold temperatures; last couple of days it has been in the low 20s and when i arrive at my destination (11.5 miles later) the light is snuffed out. at first i thought it was the battery but the light came on when it warmed up.

On my commuter I have a full range of lights, both front and rear. I was looking for something for my road bike in case I get caught out late after a club ride or weather turns nasty on a training ride. These lights are perfect. They're barely noticeable until you need them. It's just enough light to be seen as the sun begins to set or the clouds roll in. They're far to small to use for commuting, but are a great back up to have in case of emergency. And, yes, they have a flashing mode. I couldn't find that listed on any other reviews.

I got this to replace my beloved Planet Bike Blinky 3H rear helmet light (that REI no longer stock - boooo). What I like: the lights are small and light (boom-boom), and the rear does seem quite bright for such a small light. What I don't like: the front light is way too weak to be used on its own, it should purely be used as a flashing safety light (if you use this for "24hr racing" as per the item description I'd love to come watch you - assuming I could see you). Mainly though, I dislike the velcro mounts. They supply 2 velcro straps of the same length that just happen to be that too short for where I'd like them on my helmet, so they're fastened low and off-center. The simple mount lacks any angle adjustment to compensate for the mounting point. Passable 2nd/3rd safety "blinking" light for a reaonsable priced pair - but there's better dedicated front/rear lights.

The white light is not meant to be used as a means to see the road in front of you, but in order to be seen by other riders or cars. These little lights work great and are bright enough to be seen from dusk to dawn, and they'll last that long too. They can get turned on fairly easily in a bag, but buying/replacing the batteries is a very easy process. They are small and weigh very little. They do their job very well, and have given me no problems at all in the 2 years I've had them.

I use the rear Red Spok mounted on the back of my helmet. Since the Spok is small, it's incognito to the design of my well-ventilated road helmet. The white one is mounted on my handlebar. Mainly the pair is used as a secondary set of lights. Can't be used to see anything - not bright enough! I use the Blaze and Superflash as my primary means of being detected and seeing. For [$], it's well worth the extra presence of being extra-spotted on the road at night!

I purchased this product to keep in my saddle bag on my road bike. I'm usually not out in the dark on my road rides, but I've been caught off guard more than once now with nightfall coming quicker than I thought, a route needing a detour, or some other unforseen circumstance that forces me to ride home in the dusk or dark. This little light is great to have in those cases. It already came in handy once, when on a whim I decided to say hi to a friend who lived along the route I was riding and ended up riding home after dark. Having this light allowed me to make that unplanned stop, see my friend, and not worry about riding home without the safety of a light. It seems like a good quality product for this purpose, but I wouldn't use it on my commuter every day. It's a little too small and light duty for that, in my opinion.

I purchased these lights after being caught out on the road after sunset and finishing a ride in near darkness. Now I keep them in the saddle bag of my road bike for emergency use. They are light/small enough that they could be put in a jersey pocket. I have used them a number of times and am very satisfied with their performance. I would not recommend them as primary lights on a commuter bike.

These little lights are great as extras for visibility. The quick on and off mounting makes it a breeze to move them around - helmet, seat post, bag, wherever. I actually use these for a jogging stroller for night outings (every night). The white light works well mounted to the front wheel supports and not only alerts drivers, but does a good job of lighting the ground directly ahead of the wheel. The red light is nice as a safety light out back, either on the stroller or attached to me! A few notes: +The strap hugger can be turned to mount the light perpendicular to the strap - nice feature that isn't well documented increasing mounting options. +The shrouds above the lights do make them somewhat directional (not visible in all directions) so be sure to point them into traffic! And once we are off the roads, my little one loves to take them off and wear them around the driveway in the dark.

I got these lights so I could be more visible at night. They do a great job of increasing my visibility for vehicular traffic. But the headlight does not illuminate more than say 5 feet in front of my bike--so don't get this for the purpose of seeing obstacles in front of your bike. Very versatile mounting! GREAT for others seeing you--not you seeing obstacles.
