The all-new SL2 LED bulb is a direct plug-and-play replacement providing a significant upgrade in performance.Optimized Optical Focus. Don't be fooled by high lumen numbers. Your vehicle's fog lights are designed to focus light. If the light source in the housing is out of focus it doesn't matter how bright it is. You won't have a focused hotspot of light to shine down the road where you need it you'll just have more glare. To fix this the SL2 LED bulb was engineered to focus light from the same location as the original bulb preserving the focus and hotspot with no added glare. It produces a functional beam pattern with a stronger hotspot for added distance and visibility.Fanless Design. The SL2 was designed as a compact fanless solution. But that doesn't mean it's low-power! At 14 watts the bulb still provides plenty of output thanks to a copper-core circuit board and a thermally-optimized full-metal housing with integrated heatsink. The result is a highly-effective and reliable cooling system keeping the bulb running at maximum potential without the need for a fan.NOTE: LED bulbs are legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. International legality varies by country.Shipping Notes

great waterproof cell phone case.
needed a waterproof case for my cell phone when working Emergency Communications with my Amateur Radio equipment and it's raining or snowing. This should work well to protect my cell phone. Zipper seems are sealed really well. Tested the case using sink prior to using with a cell phone.

Well made and air tight
Love the little pouch it comes in handy for camping,hunting and fishing if your in not so great weather.
Not sure how the zipper is made but it's definitely air tight and can feel the difference when sealed.
The zipper is a little tough opening and closing but that's probably due to the nature of it being waterproof.
Hope it stays that way after long term use!

Nice pouch with a small opening
This is a nice weatherproof pouch.
It has enough slots for storage of small items like pen/pencil, small notebook, a bootable USB key (for emergency), and I have a fire starting kit in there.
It is well built, and I really like the materials used for this pouch. The design though, is less than stellar.
One thing, and this is a major issue for me, is that the zipper only opens at the top section of the pouch. I wish it opened more so it is easier to put things in and out of this. But I do understand that it is by design that they selected such a short zipper to keep it as weather proof as possible. The larger the zipper, the higher the likelihood of water leaking into the pouch.
Aside from that major issue, I do like the pouch, and I use it in my EDC bag.
If I need to replace this for some reason or another, I probably will not be buying this one again. I suspect that this will last a long time though.
Hope this helps.
