It is absolutely necessary to maintain the scuba lights o'rings. First of all, let after each dive your scuba light into fresh water for several hours.
Remove frequently the o'rings, clean them with a non-fluffy fabric. Also clean the o'ring grooves and remove old dust, grease, sand.....
Take a small quantity of silicon grease and apply with two fingers around the o'ring.
Put them back in place in paying very attention not to hurt (on threads as example), or tear the o'rings.
Assemble the two parts of your light, it is ready to use again !

When you do not use your light for a long period of time, it is better to maintain it removed in a clean a dry location. This will avoid the compression on o'rings and longer their lifetime.
