Thanks, I'll give it a little fiddle.

Although I should note that it started playing up on the first set of batteries, without having opened up the casing. If the normal bumps and jitters of commuting are enough to cause the contacts to play up, it doesn't provide much reassurance. A few times of coming home and finding out the light had switched off at some point is reason enough to look for another light.

Mine's done 6000km+ on about 4 sets of batteries. Never found it switched off after a trip. It's been through rain, hail and shine (but is above a mudguard).

I got probably 12k out of mine before it was pronounced "sus".

It's a bit harder to estimate the k's for the second one... But maybe similar. That means only 1 year per light. :mrgreen:

Critically I think it's the exposure to vibration that kills them - not actual operation of the light. I used to leave them on year round... But knowing what I know now I'd take them off in summer when they are rarely used.
Once you can climb hills on a bike it's all downhill. :mrgreen:

Hopefully I'll know what that's like..... one day. :shock: :lol:

Sounds like a good run from you guys.

Mine is also mounted above a mud guard on the back of a pannier rack.

Now I think back, it only started playing up the day after I rode the Main Yarra Trail from Northcote to Westerfolds park. I didn't find the ride particularly bumpy tho.

On closer inspection it seems that the culprit is probably the contacts between the battery casing and the circuit board, rather than the contacts holding the batteries in place.

Just not sure whether to apply a little bit of solder to the contacts to make them a bit chunkier.

Or send back to Cell for a exchange/replacement. Bit worried they may not run the light through enough paces to see that its not working as designed.

I agree that's the problem. I did think of wiring those contacts... But couldn't be bothered. :mrgreen:

These are the contacts I'm talking about. If tweaking doesn't get them back in the game, then it would indeed be a simple job to solder a couple of fine wires between the contacts. This would fix it once and for all and still allow the case to be opened to replace batteries.

What if it's not those contacts, and is in fact the battery contacts?

Would love you to do the experiment and report back. :)

Sure, no problem - just send your light down. Mine's still working fine :-)

So what am I doing wrong? Only time my two 'Bots (seatstay mount) give trouble is when the batteries die :?

I found they only play up for me after 15k or so of hanging out the back of the roadie in the vibration and water. :o

I thought I'd upload a video i made of the radbot 'failing' for future reference.



Now I appreciate that jolting that light with the heel of the hand is different to mounting the light on the bike and going over bumps, but its meant to illustrate its susceptibility to turn off by itself. I would hazard to guess that the jolting of the hand will definitely be more forceful than most bumps, however, its also possible that it is less force than the kind of bumps that turn the light off. Or during the course of riding, it may be susceptible to accumulating vibration that makes the contacts lose contact.

As a follow up, I posted the light back to Cell.

The idea was to buy another light to replace the radbot, and pay any difference. However, they didnt' have any lights in stock that came with pannier rack mounts, which was a key consideration for me. So they've agreed to refund the cost of the light. This is of course in line with mine and your statutory rights relating to buying merchandise that isn't fit for purpose. But overall it was a painless and only mildly inconvenient experience.

So full marks to Cell for dealing with this issue efficiently.

I'm going back to my cateye TL-LD610 with pannier rack mounts for now, and my . Its actually not a bad light. Just wish it had a bit more oomph.
