Got a friend who wants me to do it.
Is it a simple job of running 1 wire with a switch to the battery, and then an earth wire to some bodywork/chassis ?

Are they LED tubes or glass?
If they are glass, you need to run a fused live to a switch from the battery, then from there to the neon transformer. Then you connect the ground wire of the transformer obviously to your earth.
Then connecting the neons works by daisy chaining. You take the one wire from the transformer to the first tube, then the other wire from that tube to the next tube, so basically making a loop, with the last wire going back into the transformer.
If they are LED's its a piece of piss lol

wjy don't you run power to each undividually? that way theyre the same brightness alla way round and if 1 decides to die the rest will still stay lit up?

because this is the only way to wire up neon tubes? Its how they work?

a single transformer neon kit will have 4 tubes and 9500v transformer.
this powers ALL the neons.... these kits are BRIGHTER than tubes that have built in transformers.

i've seen some kits with 10,000 VOLT transformer!

i know its 500 more been told there betta then 9500 thou i got mine from neoquip 9500 and there mint

you wouldn't notice any difference... its a sales ploy.
your better with the longr tubes on ya car as it gives less 'blank' areas of light.

can you answer why they are wired in series neoquip to clear it up?

prob somthing to do with the voltage drop accross each tube is enough to make all work perfectly withought last couple on chain being dull. plus a huge 9500V transformer helps with the voltage drop too.  ...anyway. if it was parallel ther would be wires everywhere instead of simple one ring of wires.

Houckham said it about right.
its a loop all the way round the car.. the Tranny has TWO wires from it... easist way to say is one is IN and the other is OUT.
But both give power out... so as it goes round the loop.. series.. it keeps the same power to all tubes.
easy way to test this is that if you un did the furthest wire between the NEON tubes... say.. near the back... you will still find all the tubes still lighing up but when you get to the last part of the tubes that ARN'T connected you will notice they are a bit dull as the powers not going all the way around... hence when they are all connected up.. in series.. they are all bright.
does that make sense? lol

its actually the reverse of physics though? If you were to use a circuit board and some bulbs, if you were to connect the bulbs in parallel, they would all be the same brightness. If you were to connect the bulbs in series, the chain would get dimmer the more bulbs you add. ect the 1st bulb would be the brightest, and the 4th would be the dimmest.

if it were a 9.5kV transformer.
there will be: generally a voltage drop of 2.3kV across each tube.
The tube spec will be to be at full brightness when the voltage across the tube is about 2kV - 2.5kV
This is why, when all 4 tubes are connected in series there is no "dimming" effect on any of the tubes, simply because there is more than enough voltage across the whole circuit to provide each tube with enough ummph.
hope this explains it a little better.

very clever explains it spot on.
A little more oomph to my knowledge
