Well i have underbodies. I broke my front and back tube. I currently am running my side 54" tubes. I forgot about my neons one night after football pratice. Left them on and i woke up for football. Went out to my truck Found out they were on. I was amazed my truck started. That night i tried to turn on my neons. Alls i got was a FLASH then they cutout. I checked the wiring. I dont understand why they flash at first then go out. Please PM if you know the problem or have any suggestions. Its hard for me to get online alot. Appreciate anything.
