I asked this in the integra section and was told to ask here too. I have red underbody neons that were working fine til tonight. For some reason when i flip the switch, they flash on then don't glow. I know im getting power from the battery because my switch is illuminated. And im PROBABLY (please correct me if im wrong) getting current through the wires cuz they flash. So can anybody tell me whats wrong? I checked all the connections and they seem to be fine. And the fuse is not blown either. could it be the tubes, cuz they are brand new. I also have the neons running to the battery terminal in my engines fuse box if that helps any. I redid all the connections under the hood and they were fine. All the other ones looked fine too. Any help would be great and please don't flame cuz i have neons they are for shows haha( go ahead and flame as long as you help me)

 

you probably have a bad transformer, bring it back to where ever you got it installed, if you did it, sorry for ya, hopefully u have a warranty

 

if not the transformer, it's your ground

 

Definately check your ground, the electrical circuit is only as good as it's weakest ponit.

 

good call, ground too
