Absolutely, basically all the wireless thing is is a couple of switches that you wire your LEDs to and can then turn them on or off with the wireless key fob. I have my interior and my grille LEDs set up on them. I don't have a kit for the interior but I can send all the things for a DIY kit for the interior. For the stuff without the switch it's $44 and then the $42 for the wireless switch.

I've spent too long looking into the abyss. It's starting to look back.
