replacement headlight halogen bulbs

Yep,

Got me 2 new sets, with some real big relays, a fellow listmember from another list kindly bought them over from Saudi on his way back, bargain..

they are 200/260 hi low H4's.........
now to see if the reflectors will handle the heat!
Also got the Nissan Patrol/safari brocure, nice pics of the Shortie ( drool drool..)

hope you are going to run all new wires for this as the factory loom will act just like a fuse with this much juice

240W at 12volts is 20Amps

as miniumum you need 13 guage wire but I would be going with 12 guage

here is a chart of wire guage and nomimal current

Stock will most likely be 20 or 19 guage or made to handle about 5 or 6 amps.

Sure way to have an under the bonnet fire if you use the stock wire loom :twisted:

your looking at some serious light comming from those lights thats massive power hope ya got a big alternator :roll:

I dont even run the standard loom for the standard lights. The difference with a new loom with higher guage wire + relays is very noticeable even with 55w inserts.
I also got him to bring over some big ass relays and cant decide to run each side hi/low separately, making 4 relays, maybe an overkill, it doesent write the AMP rating on the relays though, if they are 50w it should be ok for 2 relays altogether.

alternator is about a 120amp or nearabouts.

Thanks for the link

how are you going to wire the 2 relays ?

even with them in parraelle they will still not handle this sort of juice for long

to run 260 W globes I would be using a 300W relay not really that easy to find

You want the globes the weakest link in this setup or be prepared for a nice warm all be it smokey engine bay

the wire loam fuses and relay's all need to handle the amount of power you want to run

relays are rated in Amps for current draw, A standard 30amp relay is ample for running 2x 100w bulbs so thats 200w. If i run 4x 40amp relays ( one for each circut) it should be ample for the lights.
I'll check with a sparky aswell just to be sure.

Yes but before you said you had 50 W relays :roll:

you are correct though relays are normally rated in Amps and this is the best way to go.

just remember power (in watts) = I (current) * V (voltage)

The rest is pretty easy from there just add in some room for over current faults and use a fuse to prottect from over current they are cheaper than a relay or your wireing

this sounds very interesting but...

...are you planning on using 200 watt low beam on the road???

hope Im not coming towards you at night!!!

you'll have to tell us what the cops do when they see u coming

nothing good i can imagine!!!!!!!!!!!

probly show u some lights of there own

I don't think the reflectors will handle that wattage globe for long...
It seems that a lot of people think that putting high wattage globes are the only way to get good light. The condition and quality of the reflector are more of a benefit than big globes. Look at late model european cars and the light they get out of their headlamps> They can fit only 60/55w Zenon (blue) globes.

HIDs are only 35w...

Just my 2c worth.........

Whats wrong with 100/80w lights & a coupla good spotties?? IMO gives you good light on low beam & great on high. :roll:

And don't blind the on comming traffic!!!! So good for everyone!!!!

Low beam has a cutoff line that is visible when you drive the car upto a wall, this stops light being thrown above a point into oncomming traffic.
Bit of a bugger at crests but you get that.

as for why.... hmmm.... same reason i have a 600hp small block in a 4wd.....the solution to every problem is More (horse)power.

I am guessing the reflectors will give up the ghost quick smart, but i am remaining optimistic.... just as well i have access to a wrecking yard full of H4 headlights.

BTW, finally wired up the lightforce 240's up last night and adjusted them... pretty GOOD..... needs difuser for one though.
