Using With Automotive Brake Lights

Some automobiles have neon brake lights, which are powered by neon transformers. Often when the brake lights fail, the neon tube is good and only the transformer needs to be replaced. Usually this requires 1 neon transformer per neon bulb (but it depends on make of car, so you must know your vehicle's requirements). Most manufacturers have a replacement solution costing into the $700 range, however a much cheaper solution is to use of 2 of our DC-series automobile transformers, sold here. Please note: you must know the electrical requirements of your own vehicle - we have no way to provide this information and cannot guarantee performance with your vehicle as we do not know its design parameters or electrical configuration. We can sell you the components, but you must know how to install them and how they work with your vehicle. Please note there is no refund on these units due to the fact they are being used in possibly incompatible circuits, however these problems are rare.

The diodes our customers have had success with (RECT6A600V rectifiers for making a 2-step ballast) are available here for purchase. You may need from 1 to several of these per transformer to achieve the required differential brightness between running and brake lights (this will depend on your vehicle and its setup, so the user forums or a vehicle repair manual may let you know). By request, below are forums that customers have recommended (note that we do not guarantee the information on these websites, and any information used is at your own risk):

NEONXA - 4kv 20ma (fully potted)

Instructions

Using With Automotive Brake Lights

Versatile weatherproof driver for automotive or general outdoor use (may also be used indoors, but is designed to withstand outdoors use). Can be used for a single-ended or conventional double-ended display. Operates from an automotive battery or any 12-14V DC 2A power supply (not included) and drives up to 10 feet of display. Higher amperage batteries or regulated power supplies will not overdrive this transformer, as it will only draw the current needed to power the load. Output is 4kV at 20ma, at approximately 30kHz frequency. Unbalanced output greatly simplifies install since only one high voltage lead is required and can be only several inches long depending on driver location. The return lead, usually coming from the far end, needs only to be grounded to the auto frame or be a low voltage wire. Fully potted case is 2.75 x 1.75 x 1.25" with a 3.5" aluminum heatsink/mounting bracket, weighing 6 ounces. If you need a 12V DC power supply, our 12DC/2AR works very well with this transformer.

NEONXA - Automotive End Point Unbalanced Transformer ... $49.95 
RECT6A100V - 6A 100 Volt Diode ... $6.95

These low cost high voltage balanced output transformers are intended to be used in any vehicle with a 12 V system. They also can operate from a 12 volt battery for portable use, or can use a wall adapter for normal 115 vac outlet use. Virtually indestructible circuitry is open and short circuit protected and will withstand reasonable amounts of EMP and other abuse. Output is ungrounded and at a high frequency of 25 to 35 khz. This higher frequency allows easy conversion to high voltage DC sources using voltage multiplier stacks. The direct high frequency output easily powers 2-electrode neon displays such as place stands, small point of purchase displays, home neon, vehicles, etc. All models include appropriate input and output leads for easy terminations.

NEONXUL - 3kv 15ma

Endpoint Grounded for Small In-house Displays

neonxul

3kV open circuit at up to 15ma short circuit (2kV 10ma under load), requiring 12vdc 800ma power (adapter not included). Full short and open circuit protection, suitable for battery operation. Full metal enclosure 2-3/8 x 1-1/2 x 1-1/8" in size with 3-3/16" mounting centers, 7" input leads and 18" output leads. This is an excellent hobby unit as it is virtually indestructible and can be used with a voltage multiplier to generate up to 20kV at 1ma with our 4-stage multiplier (CH20), or 30kV at 0.5 ma with our 8-stage multiplier (CH30) at a low safe current. It is an excellent driver for neon displays of up to eight feet, and this unit is also used as the driver for our HV250 high-voltage DC power supply which produces 25,000 DC volts.

for Battery or Solar Applications and Special Display Effects

Great unit allows total dimming without pulling of ends away from electrodes
Provides an even distribution of light along the entire display length down to where discharge appears as a wriggling worm at it's lowest setting...THIS IS AN ALL NEW, REALLY NEAT EFFECT

dc20 transformer All new power supply for portable, solar or battery powered neon and gas tube displays. Operates any normal display up to 10 feet and allows complete dimming without pulling from the ends. Excellent for powering hand held plasma globe wands or similar devices offering a wide adjustment of display textures. This is an unbalanced system that will work well powering small conventional double ended neon displays.

Circuit design is virtually 99% efficient and is a real advantage for solar and battery power where every watt counts. Board level layout is 5 x 2" and is simple to use. 12" input and output leads with dimming control. Uses our 12DC/5A wall adapter (below) and draws 2.5 amps when operated at full output (Not Included). For field use, it will run from any 12V battery with at least 1.5A output. Dimming control will reduce current to less than 0.1 amps and allow operating from solar cells or batteries for hours or even days.

NEON21 - 7kv 10ma
minimax7 These low-cost, high-voltage sources operate from a 12 volt battery for field use, or a wall adapter for normal 115 vac use (wall adapter sold seperately if needed). Virtually indestructible circuitry is open and short circuit protected and will withstand reasonable amounts of EMP. Output is end point grounded and is at a high frequency of 25 to 35 kHz. This higher frequency allows easy conversion to high voltage DC sources using voltage multiplier stacks. The direct high frequency output can be used to power plasma and gas discharge (neon) display tubes. All models include appropriate input and output leads for easy terminations.

This device provides a 7kV open circuit 10ma short circuit output that requires 12VDC @ 1 Amp input. Open frame with potted transformer 5 x 1-1/4". Easily generates 30kV at 0.5ma with our MULTI50 five stage multiplier. Also used in our HOVER (experimental hovercraft), KIRL1 (kirlian photography), and PLPEN1 (plasma burning and etching pen).

Circuit design is virtually 99% efficient and is a real advantage for solar and battery power where every watt counts. Board level layout is 5 x 2" and is simple to use. 12" input and output leads with dimming control. Uses our 12DC/1.5 wall adapter (below) and draws 1.5 amps when operated at full output. For field use, it will run from any 12V battery with at least 1.5A output. Dimming control will reduce current to less than 0.1 amps and allow operating from solar cells or batteries.

NEON21 - Transformer only, without wall adapter ... $49.95


12DC/2AR - 12V wall adapter for NEON21 (except as noted below) ... $12.95
14DC/1G - 14V special grounded wall adapter for single-ended neon displays ... $19.95
* Use this 14V wall adapter if the NEON21/MINIMAX70 transformer will be used for a single ended NEON GAS display for special effects: this is where the neon tube is powered with only one wire and the return of the energy is via the capacitance of the gas and the surrounding air eventually going to earth ground. This mode absolutely requires the use of our 14DC/1G, a 3-pin internally grounded wall adapter for this capacitive ground current to return back to the power supply source.
