Roof Lamps
jjsaul:
i'd be careful about mounting fogs up there...glare might be an issue...as well as them being illegal for road use, AFAIK fogs have to be below a certain height? driving lamps are fine.
ps dont drill any holes in your roof...they WILL LEAK.

Ok, so Relays, is that it then, and also, would it be better to try and get a bar to mount them on (Next time I'm at my mums I'll get pics of the lights)

And don't forget to fuse the live feed, and use cable that can carry the total load.
(not wishing to teach you to suck eggs, but here's how to calculate what cable and fuse size to use)
Take the total wattage of the lights and divide by the voltage, the answer will be the current draw in amps.
eg: you want to run 2 x 100W lamps from a 12v supply
200W / 12v = 16.6A.............so the cable needs to be able to handle at least 16 amps (I'd run 25A cable), with probably a 20A fuse. Don't ever be tempted to use a fuse rated higher than the cable !
And please, don't use them horrible scotchlok connectors - crimp or solder is best.

dew1911:
I'll get some pics of the lights - Not sure what kind of bar I'd need as they are not usual Roof Lamps.
Henry Webster:
Will your alternator be up to running all those lights?

If you're unclear of the legal issues, there's a link to the appropriate bits of law here:
