What I have done depends on the type and shape .On most vessels I build they have the clear shock-resistant clear globe with a metal cage around then .
On vehicles I usually find this to work . For inside lights take a piece of plastic the shape and size you need .Cover it with bare metal foil then clean the edge off for the next step .Get some .010 strip and build the edge and epoxie it in place .Super Glue will not cut the mustard here !
Now in the internal space cut and fit a clear piece of plastic that you've sanded lightly with 600 grit on one side Cut to fit in the resulting depression . Now sand the clear smooth with the edges you've already built .
Smooth the exterior nicely and paint the edge the color it's supposed to be .Polish the lens gently and there you have it , one interior light for your Husky . T.B.
