Hi Cruising Cruze

You'll need to install some resistors into a separate line out of the house batteries as it's own circuit.

For an exact explanation or probably somebody like Dorian would be able to give you good advice, try a PM.

Perhaps if you explained what you want to do (LED Lights I'm assuming) then there may be a much simpler method.

Cheers

Mark

Thanks Mark for the fast response

Yes indeed for led lights

I was just thinking maybe via an USB socket,
but I would not know how much I can pull out of that

got a set of bunnings ,they are prity handy was looking for 12 volt spotlights they are way to money

Hi

We will need to know Exactly what you wish to use 4.5V for

The   description  & Wattage of the device will be a good start

Reducing the voltage by means of resistors has limitations & in fact in some cases simply cannot do the job .

Get a cigarette lighter transformer with adjustable voltages,,,, Repco or Jaco etc.

Just set one up 12v to 9V for radio/cd player so wife doesn't have to buy batteries,,, output of mine is 1.5A

Hi John

Have a trawl on the web, there are a number of companies that make direct replacements using a circuit board, "plug & play" but as you say, they ain't cheap!!

Good luck

Mark

Thanks Sheba

That's twice today it hasn't taken the link!!  
What am I doing wrong.  I normally right click from the URL and select copy, and then paste it where I want it and it works, not today!! 
Advice would be gratefully appreciated.  
Send me a PM, don't want to destroy original thread.

Cheers

Mark

Hi Aus-Kiwi

Just tried that with the above link, which is how I would normally have done it, thanks for confirming my actions, and it's done the same.  
Strange, it has worked before!!  Maybe the PC is having an off day.

Thanks for your suggestion anyway.

Mark
