Have You Serviced Your Backup Light lately?

Halcyon LED Scout Backup LightI learned an important lesson about servicing my backup lights several months ago on a night dive at Veteran’s Park (Redondo Beach).  We were out of the canyon and just screwing around to at between 20 and 30 feet when my buddy Mark’s primary went out.  I was almost giddy at the thought of finally using the backup light I’d been wearing strapped under the arm of my BC for god only knows how long.  I followed proper deployment protocol by first twisting the light on, and then unclipping it from my D-ring and passing it to my buddy.  My UK 4AA eLED lasted roughly 30 seconds before it flickered out.  Who knows if it was sand or crystallized salt that broke the seal as I twisted on the light but one thing was for sure: That o-ring hadn’t been cleaned and lubed in quite some time. 

I’ve been thinking a lot about building a tech rig lately.  The failure of my backup light didn’t seem serious at the time, but now that I’m thinking about tech, I’m taking these little lessons much more seriously.  These days I wear two backup lights packed with fresh non-rechargeable batteries.   On one side is my Halcyon LED Scout and on the other is a cheap 4AA I found diving Catalina.   I test them both before every night dive and service the o-rings regularly.

    I always use silicon grease on my lights and camera housings every four dives. Yes, I’m paranoid.

    Thanks for the link, I’ve added you to my blogroll/links section.
