FlowLighting Cold Cathode Light Kits
Forget traditional neon - cold cathodes offer a stronger glow for your car lighting design, but at a fraction of the cost of the standard neon lighting kit. These amazing kits include two cathode tubes in your choice of colors, and a dual output transformer to make them run like a dream.
Easy to install and packing a punch that you won't expect, these dual cathode lighting kits come in 12" and 4" lengths and a variety of colors.
Each tube consists of glass contained inside a protective acrylic tube, and is guaranteed not to break unless the surface they're mounted to flexes and bends. This amazing, inexpensive lighting option features standard polarity protection, for added protection against burn-out. The transformer is housed in a 3.25" x 1" x 0.75" black plastic safety housing.
Hook your cold cathodes up to our Oznium.com switches for an even better effect, and you can have the entire package, ready to install, for under $10!

FlowLighting Cold Cathode FAQ's
How many cathodes does this kit come with?
1 cathode kit consists of: 2 tubes, and 1 transformer (with a red and black power wire). The 12" kit looks like this, and the 4" kit looks like this.
What exactly is a cold cathode?
A cold cathode is a lamp very similar to a neon lamp. The light comes from a small round neon tube (2.6mm diameter) powered by a transformer. The transformer is designed to use 12 volts DC, and output approximately 650 volts AC that is needed to power the cold cathode.
What is the difference between cathodes and neon's?
The main difference is in the light output and cost. Cathodes are much brighter and less expensive than regular neon accent tubes. Cathodes are a better value.
What are the cathodes made of?
The cathodes are made of glass with a protective acrylic tube around the glass. They will not break as long as they are mounted to a surface that prevents flexing and stress on the tube.
Do the lights get hot?
The glass and ends of the lamp do get a little warm, so they should be installed so that they do not touch any material that might be flammable.
Can the cathodes be used outside?
Yes, but you should first seal the tubes and transformer with a silicone sealant and possibly a few layers of electrical tape. Alternatively, You may consider using our Flexible LED Strips which are already waterproof.
Can I extend the white wires past the transformer?
While it is possible, we do not recommend extending the white wires past the transformer. The cathodes may dim and flicker from the loss of voltage. If you want a cathode on each side of the dash, just buy two complete sets. You can however, extend the red and black power wires to reach the battery, or other power source. If you need to extend the cathode tubes past the 11 inches, we suggest you buy either an extra set of cathodes, or buy an extra transformer.
How long are the white wires?
The white wires are 11" long. So that means, you could put the 2 cathode tubes about 22" apart from each other.
Are the red cathodes really red? What about the orange cream?
The newest style cathodes are quite red. The orange cream cathodes are not very orange, but more white with a hint of orange.
When hooking the cathodes up, does polarity matter?
It matters, but nothing bad will happen if you accidentally reverse the positive and negative wires. The transformers have built-in polarity protection.
How many amps does a cathode kit use?
Each cathode transformer draws about 0.7 amps of power at 12 volts.
How do I install the cathode kits in my car?
Please read this comprehensive topic in the Oznium Forums.

Bought a few kits and they've been great. Bought one recently and one of the bulbs was much dimmer than the other. I notified Oznium and they sent a whole new kit free of charge! I'll be buying more kits soon!

Reviewer: Anthony (Snow Hill, NC)
Cathodes are bright and were perfect for my lighting needs. Even though less than a week after install, 1 of them burned out I still rate this a 5 star because Oznium sent out a replacement the same day no questions asked. Great customer service.
Great Product and Great Service | Apr 15, 2009

I had originally purchased Logisys Cathode lights and although it worked, the lights started to dim after a month and the inverter was crap. especially if you plugged the wire the wrong way, the inverter was shot. I then found Oznium through word of mouth and never looked back. With the Oznium cathodes, they have been in my trunk in very very cold weather and hot temperatures for almost a year. The light is still bright as when I had it the first day. I have modified the cathodes to work in the trunk using a 194/921 wedge plug or 3022/3021 festoon plug.
Here is how they look - http://www.cardomain.com/ride/3144992/3
I have sold many of my kits and there has not been any complaints at all. The customer service is also superb. I had a inverter that fried with a burnt smell and Oznium was quick to send out a replacement!
great service :) | Mar 09, 2009
Reviewer: Angelo Lodati (Union Bridge, MD)
