My main worry with purchasing these was that one of the interior lights in my semi is reverse polarity, and the other is standard (verified with a multimeter). I've had various 1156 LED bulbs fail in the reversed socket, which is due to the nature of LEDs, but research indicates that higher quality LEDs can make use of any polarity, with the proper 'drivers'.At any rate, I got these and gave them a shot - sure enough, they work in both sockets! I'm thrilled. They definitely get hot if left on, but not near as hot as incandescent. If you're expecting entirely cool, this isn't it. But an inch away, you won't feel any heat at all, and you can certainly touch them without getting burned.As far as brightness, images don't do them justice. They are a brilliant white, which I prefer to the almost yellow of incandescent, and far far brighter than the brightest 1156 incandescent you'll find. I'd day that in my application, they easily rival daylight brightness, and certainly reduce eye-strain when I'm doing things in my truck at night.In my picture, I've got bright incandescent bulbs installed in one fixture, and the LED bulbs in the other. Each fixture takes two bulbs... And they are literally the same fixture; same plugs, internal reflectors, and covers. They take the same voltage, but are on different circuits in my semi. These two fixtures even have the same polarity. And... Well. You can see the difference. And that doesn't even do it justice.I'll gladly recommend them to anyone who needs an 1156 for just about any purpose.I tested these in a 2015 Freightliner Evolution, in both the dome lights (standard polarity) and the map lights in front (reverse polarity).
