PlanetBike superflash won't turn off

The button on my PlanetBike Superflash appears to be broken, as it won't turn off the light after putting in the batteries. Anything I can possibly do to fix it?

Remove the light from the holder base, as you do when you change batteries. There is a small push button on the bottom after the unit has been halved. Try to activate the switch this way. If it still fails to turn off, you require a new switch at which time you will need to be a good solderer or you will need a new light.

Ok, yeah I already tried that, so I guess I'm out of luck. Maybe I'll carry around the batteries and stick them in when I need to use it, lol.

I have worked with that style of switches quite a bit. If the solder joints are good, then clean the switch with alcohol.

There instructions are generally for when the switch will not turn on; however, they may also work for "wont turn off"

Get some alcohol and q-tip style swab. Turn the switch so the button is pointing up. Then thoroughly wet the swab with alcohol. It should be nearly dripping. Then place the swab on the button and pres repeatedly and frantically. What you are trying to do is to fill the switch chamber with alcohol while repeatedly making and breaking contact. This is to clan any crud off the face of the contacts (like I said, this is normally for won't turn on).

Thinking about this, I have successfully done this for button switches that will not break contact.

I used to work on Copiers and the whole control panel is made up of these type of switches, under the cover. I used to have to repair these switches quite often.

I used hand sanitizer and a kleenex (I probably should have waited until I got home to use your exact recommendation), but it appears to work! Thanks a ton!

That's funny. That is my experience as well. Very commonly used as start switches on copiers. Used to carry tons of them and solder new ones in all of the time.

If you're going to be getting a new light anyway, check out the Radbot. I don't have one but they look like they pretty much spank the SF. I have a fistful of superflashes, but if I ever have to buy another rear light I'll get a Radbot.

This one from Performance looks like the SF but is much brighter (and $14.99 on sale).
Got 2 of them to put on the kid's bikes...liked them so much I got 3 more to augment the SF's on the spousal unit's and my own commuters.

I've had 3 or 4 PBSF's and all the switches were difficult to operate. Maybe it's time some other manufacturer got my business.

And if you're on a budget and can wait 2-4 weeks for your light to arrive, get this this light from dealextreme.

I'll start out by saying it's not as good as the PBSF. But it's very similar, and I'd say it's 85% as good, and cost 85% less -- at $3.54, if the switch breaks, you don't feel bad about throwing it out. The mount is also compatible with the PBSF one, so it's a drop-in replacement if you want.

The last time I wanted to buy another PBSF, I bought 10 of these lights instead. I mounted two on my bike, keep some more in my bag for friends who need something, and still have some spares in case I need them.

That said, I've got a friend who has the Radbot. It looks like a great light -- similar to the PBSF, but with a more interesting flash pattern. Is it better? Hard to say, but being somebody who pays attention to bike lights, it certainly gets my attention more than the "common" PBSF does now.

Here's my review of the DX light that Doug mentions above:

http://www.bikeforums.net/showthread...illight-review

If I were buying a small portable light to be my only taillight, I'd get the Radbot anyway, I'm not going to screw around and try to save a few bucks on my main light. But I have a Magicshine rear light, these are just for backup and additional visibility, so I am OK with using these instead. FWIW I think the same of the Superflash - it's OK if you're just riding on low speed streets in good weather, but not good enough for bad weather or high speed roads.
