      Worked well for me

          Comments about RadioShack® 12V/20mA 4mm Red LED with Holder:

          I bought this as well as the same thing in green to use in a homemade footswitch to switch channels on a guitar amplifier. Would not have trouble seeing them on a sunlit stage or in any lighting conditions really. I like the way it mounts fairly flat as well. Just installed them today so hopefully they will stand the test of time. As long as that isn't an issue, I would recommend and use them again.

          Comments about RadioShack® 12V/20mA 4mm Red LED with Holder:

          I used these LEDs on my model railroad control panels. They were easy to install using 9/32" holes. They are nice and bright and look very professional.
          They have not been consistently available online for the past several months, and stores usually stock 1 or 2, so it took me longer than I would like to obtain the 25 I needed. these are proprietary to RadioShack, so they are hard to find elsewhere.

                Just wanted to add that this product includes a built-in 680 ohm resistor. I installed this in my kitchen to alert me when the garage door is open.

                be cautious when tightening the nut... it will snap the head of the led off.. i've not found a consistant torque. i'm going to use silicone to keep the nut from backing off

                    I purchased 8 in total. Nice design. However half of the 8 are dim and the other half are bright. The circuit is parallel not series. Havent made an attempt in turning in for warranty. Kinda scared to do all the work for the same results.

                        Used these to replace indicator lights on cars, RV and motorcycles. Work very well. Almost as bright as the incandescent bulbs they replaced. No more worries about bulb/socket corrosion and vibrations (motorcycle) don't bother them. Great for reducing current load on systems (especially motorcycles).

                        Would like to see something done about seeing them in daylight, but, they are just LED's.

                                Its not the led's problem, you simple wired it wrong. You wired it so that the led is "hot" all the time. You need to run a hot to your switch, then the hot running from the switch will connect sirens lights and the led all together. That way when you turn it on those all come on, and when you turn it off then the led will go off. Its a simple procedure, but if your not experienced then its easy to mess up to.
