Glad to hear of these new designs that are worthy of the waterproof claims. Many non-L.E.D. designs' weak points were the need to disipate the heat generated my an incandescent bulb. LED's solve this.

Thanks to you all, I am nearly motivated to add trailer lights and dispense with my funky, strap on light bar.

I'd like to mention that there is an upper-end type of shrink tube that has glue inside it so that it not only shrinks, but creates a seal also. (that is the product's claim, I have not tried the stuff yet)

I'll bet those who own glue guns could do some great things with them to aid in waterproofing.
