Most of people don’t know how important the O-ring is. In fact, they usually neglect it. They take care of the lamps, the battery but few people take care of O-rings. Probably, it’s because it is really cheap, so people undervalue its function, which can prevent water leaking into the casing of light. Because of a failure of the O-ring, the flooded light problem will come to you!!
The professionals all know how important the O-ring is, so they do carefully the maintenance with it. Here are some tips for your reference:
1. Remove the O-rings one by one. Sometimes, in the light there are more than 4 O-rings which are very close in size. If you remove all the O-rings together, you might put them back in the wrong place.
2. Clean the O-rings, make sure there is no dust on it.
3. Put some silicon gel on it. Don’t put too much, otherwise it will stick the dust, sand, hair or any thing, which might damage the O-ring and cause the leak problem.
4. During the process above, do not stretch the O-ring. Or it will lose its function.
You have to do the maintenance regularly to care for your waterproof light(s)
