G'day Ryan,

I'm assuming you meant 240V, in which case either of these transformers will be just the ticket.
Which every one you go with (they have different Amp capacities) will depend on the size of your lighting system.
If its just this kit, the 36W transformer should be ok, but if you want to extend it or add more lighting in the future, go with the 60W option.

G'day Paul,

You can just pick up a 12v cigarette double adapter from Jaycar or similar, which will allow you to run 2 x 12v cig appliances.  As long as your load doesn't exceed 10A you'll be fine.
If you have an Engel or new Dometic you should have the posifit terminal which will allow you to utilise the 2-pin output.
Hope that helps.

G'day Adam,

The Lifestyle 4 Bar Orange & White kit comes with two different dimmers, one for the white bars, and one for the orange/white bars. If you have a look at the beginning of the comparison video Ben outlines these two dimmers, they are the dimmers supplied with the Lifestyle Kit.

G'day Jemma,

Yes, they do require a 12v power source to work, so if you do not have a portable battery system or solar panels, etc you'll need to plug it into the 12v port of your car.
Fortunately, the draw of power on these light systems is quite low, and you'll only really have need of using them for a couple of hours max each night.
If there is any concern you can occasionally start up your car and let it run for a bit to keep your battery healthy, via the alternator, if you are in one spot for several days.

G'day Sam,

The 2.4A power consumption if for all 4 bars, so if you used 1 or 2 you would use less.

G'day Matt,

I've just checked the specifications that Hard Korr list for the motion detector, and they indicate it needs to be used instead of the dimmer wheel that allows switching between white and orange. We don't actually sell the Motion Sensor Kit, so we've not tried it out, but based on the information on the Hard Korr site, I don't think you'll be able to get them to swtich on in orange mode. 

G'day Matt,

Yes, you can add extra bars into this set with no trouble at all however you would need to limit each string to 2-3 light bars.
If you need more than 2-3 light bars, you can add them on a separate string of lights with their own dimmer.
