Today I went to use my NiteRider Lumina 650 bicycle light but upon pressing the button, it simply wouldn’t power on. Naturally I assumed it simply needed charging but I connected it to a charger, instead of either the usual red light to indicate it was charging or blue light to indicate it was fully charged, I got both red and blue lights simultaneously.
A quick Google search showed this wasn’t an isolated problem and there are reports from lots of people having this issue and not being able to fix it. Unfortunately for me, my light was out of the 1 year warranty period (although the light was hardly used).
It turns out that the red and blue light combination indicates a problem with the battery. If your unit is fairly new, this is almost certainly down to a simple flaw in the Lumina series of lights where the power connector pops of the controller board. The connector Lumina have used is a ‘pop on’ type connector rather than one that slights on to pins and a bit of bouncing around can cause this to pop off, at first glance it can be very hard to see this, here it looks to be intact but is not:
The quick fix is to simply pop it back on but for a long term fix I would either fix it in place with superglue or with tape.
Bear in mind glue is going to make it much harder to replace the battery, which can be bought online from the NiteRider website: http://www.niteriderstore.com/index.php/replacement-batteries/lumina-battery.html
