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?

Great Products | Jan 03, 2009
Reviewer: Adam Brink (Florence, AL)
Ordered a 12" and 4" kit with a wedge toggle switch. Came in about 3 days. Easy to set up, works great. Brighter than StreetGlow neon. Very impressed will order again.

Reviewer: JG09 (East Moline, IL)
these are the brightest lights I've ever seen and they're extremely cheap. I put a 12" blue cathode in each front foot well and a 4" green cathode in my glove box and dash console with a lighted rocker switch for only $29 and they work amazing. The best part about them is how easy they are to install. Great product and service, definitely going to be coming back to oznium in the future.

Reviewer: Erik (Schererville, IN)
these lights are awesome. they are not too hard to wire in and they give off a ton of light. definitely brighter than any led or neon i've tried. i'd strongly recommend these to anyone looking for some sweet, and very fairly priced custom lighting for anywhere in their car.
Amazing product! | Oct 12, 2008
Reviewer: Nathan Rahm (Milaca, MN)
This product is great. The cathodes are super bright. I set up two blue cathodes with a mic in my closet (which is where all of my electronics are set up). They light up my whole closet every time the bass hits, it's awesome!!! plus they got here like 2 days after i ordered them..
Smaller, brighter & CHEAPER than neon! | Oct 03, 2008
Reviewer: Paul (Ontario, Canada)
I replaced my dim factory trunk light with a blue 12" cathode kit. What a perfect even glow that effectively & attractively illuminates the entire trunk.
Exactly what I wanted. Thanks Oznium, I'll be back for more & I'm sending my friends your way.

Oznium Rocks! | Sep 27, 2008
Reviewer: Darren Milner (Kosciusko, MS)
I recently ordered some cathode lighting kits from Oznium. Not only were they purchased at an unbelievable price, they arrived at my door about 2 days after ordering without any type of 2nd day shipping. I can't recommend them enough. They even followed up with me after ordering a second transformer to be sure that nothing was wrong with my original order. They know how to take care of their customers. Thanks Oznium for a fantastic product and supplying me with the final touches to my guitar pedal board glow top. I know I'll be ordering again.

GREAT for in car lighting | Aug 30, 2008
Reviewer: Ethan S. (ethanFBM) (Gilbert, AZ)
these cathodes are awesome for in car lighting, they are super bright and easy to work with. i had a transformer blow a few weeks after purchasing and oznium sent me TWO replacements, so of course i gotta mention oz's amazing customer service
the ONLY reason i gave 4 stars and not 5 is the white wires from the transformers to the cathodes could be a little longer to make hard to reach spots less difficult to light up. other than that an OUTSTANDING product, would and have recommended to everyone
