LED "Frequncies"? What does that mean? Electronics technical consultant here for +30 years. A 12V 194 LED replacement bulb should not make use of any "frequencies". That would imply some sort of inverter power supply which a simple 194 LED would not have.
Plus. . it is up to an aftermarket company to research, develop, make and sell a product that does not cause any malfunction in the vehicles it is sold for. . . At least, that is standard industry practice if not a good business practice.
I just checked again and my 2017 Colorado LT CCSB has no remote control "delay" or any other anomaly caused by even the low cost generic 194 type bulbs I use in three GM vehicles including two 2017 models.
Just surprising DD did not seem to do their homework on this since they seem to have such good quality other products.
I've used 194 bulbs like the ones below in both non CANBUS and CANBUS iterations. The CANBUS type LEDs are obvious in that they will have resistors and/or associated electronic devices usually present on the bulb as the second picture shows. Some LED makers shroud the bulb packaging resistors are not apparent.
Maybe frequency was the wrong word to use but the fact still remains that these bulbs interfere with the operation of the remote on my truck. When I turn them off the remote works perfectly so there must be some sort of interference or something from these bulbs that affects the remote signal, I don't know. When I told the dealer of this problem the first thing they asked me, after looking up the problem, was did I have LED interior light bulbs in my truck. I don't care if you don't believe that this is happening (or can't possibly happen because of your many years of electrical technical consulting and knowing everything about LED bulbs) with the use of the DD LED interior bulbs in my truck. It is what it is and if you want to wrap yourself up in your 30+ years of electrical consulting experience, maybe you can figure it out....just because you don't have any problems like this with your truck means very little to me because your truck isn't my truck.
