I have been using one on my Honda Civic that i had a Neon under body Kit on and it worked awesome, I never had issues with it. I now have a 2008 Scion XB and i am about to install a neon under body kit and interior LED's and I will be using a new PlasmaGlow switch that i bought to turn it on and off. I have already tested the new switch and it works like a charm!
