Performs as described. Only drawback is you can’t shut them off when not in use and they drain the expensive batteries.
Product was totally unacceptable and non-functional. Button batteries provided with product were corroded inside the package and not visibly apparent until after I got it home from ship to store and opened the package. I have previously purchased a similar product "off-the-shelf" in the store and it worked just fine, being of slightly different configuration and manufacture. All I really need is replacement batteries, also button-style (LR1130) for the original valvestem capa, but they seem to be largely unavailable or highly over-priced. I am completely dissatisfied with this purchase and return cycle.
4 out of 6 batteries had corrosion in the packaging. 6 replacement batteries cost $26 @ local Radio Shack. Battery installation diagram on the packaging is tough to decipher, so you've got a 50-50 shot of installing the batteries the wrong direction. If you do the "little beasties" start to generate some heat due to the short-circuit discharge. Hint: install the batteries so that the top of the batteries (side with writing) faces the wheel rim/inflation valve. Screwing the caps onto the wheel are a little tricky, you have to adjust the cap so that they flash brightly, possible they can dimly flash due to a poor fitting. There's a clear white rubber gasket (hard to see if you drop it) that seals the cap from water. The gasket kinda reminds me of the clear/white rubber washers/bands that kids use on braces. Be careful not to over tighten the cap be ause you'll pinch/loop out the gasket & thus defeat the purpose of the water barrier. Once you adjust the caps, they work as advertised. LEDs are not bright enough for daylight -- product is best for low-light conditions (i.e. dusk, dawn, night). I like the fact that the lights continue to flash 5-10 secs after motion stops, e.g. A momentary pause at an intersection. Any bump, not just rolling motion will get ' em flashing again.
Very bright motion activated lights. Haven't installed them yet as it's still light pretty late but will start using them soon enough
