Arline, small LED lights, like on your smoker, are VERY hard to make bright enough to view in bright sunlight. If you shade your smoker, or cup your hand around it, you should be able to see it. MORE IMPORTANTLY: Is there hot air coming out of the top vent hole? If so, your smoker is working. If not, it may not be.
Also, the times that you've used it (even the time you say you couldn't see if the light was on),
did your food cook? Now, it is possible that your light has failed...it's rare, but it happens. It's not a big deal to change it out. Contact Steve and let him know that you can't see your light. He'll send you a new one. This is a minor thing, but I respect that it is important to you. Call Steve.
Before you call, however, I recommend plugging your smoker in during the evening, turn it on, and see if the light is functional or not. Bright sunlight is tough.
