I’ve seen a number of people mention that their helmet has “a few diodes out.” How would you know. Is there an easy way to check if all my helmet’s diodes are working without exposing my eyes to 300+ diodes?

Not an expert, but generally bad diodes will get hot - so, your can locate those by running your fingers over the diodes.  I purchased a set of glasses on eBay which are specifically made to allow safe viewing of diodes in the 650 nm range.  Here’s one, if you are interested: http://www.ebay.com/itm/CE-Red-IR-laser-safety-goggles-glasses-OD6-600-1100nm-633-755-808-980-1064-etc-/251305151879?pt=LH_DefaultDomain_0&hash=item3a82f44d87

Quick way of checking is to put a blank sheet of A4 paper right up against the lasers.

You`ll soon know which ones are low or out.

I wouldn’t worry about eye exposure looking at
the lasers medhead.. you can usually “feel” a bad
/dim laser before that anyway, it will feel very hot
On the scalp when your using your helmet..

So you,ll now roughly where to look then.. And when
Looking at the lasers its just a quick look really,
you,ll spot it easily, it,ll be very dim against the
other lasers.. Try and locate and remove it sooner
Then later!

Good luck.

I was under the impression that this particular kind of laser was relatively safe to look at, if it’s only a quick look for a few seconds. I’m pretty sure I remember reading somewhere that OMG sometimes did that to locate bad diodes, too. I’ve done it a few times with no ill effects. Just make sure you don’t stare for too long.
