I've decided to replace the waivering ammeter in my headlamp, and wonder how best to seal it, if at all. My first thought was to put an appropriately sized o ring between it and the headlamp. The ammeter is fastened to the headlamp by 4 little metal tags, which bend down under the hole in the headlamp. They seem pretty short, and I wonder if an o ring will be too thick to enable these to attach properly. Second thought was some silicone sealant. Third thought was no sealant at all; just metal on metal; but I am conscious of the bundle of wires in the lamp; and concerned about the damage that might be done if moisture gets in.
Any advice?
