Cab clearance lights holding water

[Rogan]

I noticed this morning (we had some pretty decent rain yesterday from Ida) that 3/5 of my cab lights are holding about 3/8" of water..  I ASSUME this is coming in through the screw holes, since there are no cracks/etc in the lenses. 

Is there an availability of small screw washers/seals out there somewhere that you may know of (short of some clear silicone or something)?  I don't want this to create bigger problems in the near future.

 

Thx

Probably local hardware store has some plastic washers, they have new gaskets/seals online I've seen before come as a kit with washers. I need some too.

my 02 had a problem with that at 4 yrs old. I put small O rings on each screw head around the shank and the problem was gone. Still no problem.

Harbor freight you can get o ring sets for super cheap. Ive got a set in the service truck (Thor).

I checked 'em out, but the smallest in the kit was 5mm, which is too big.   Advance had 3 o-ring that were the right size, but that's it.  I'll try Lowes tomorrow I suppose.
