Guys, here is some very useful info from another thread, makes wiring your new spotties easy and also a new upgraded loom for your headlights.


The top diagram is for negative switched Headlights and the lower diagram is for positive switched.

A basic headlight wiring up grade and you don’t need to know whether the vehicle is positive or negative switched, the wiring sorts it out automatically.

One thing I would change is the cable between the battery and the fuse block, this should be at least 6mm to give the best results.

A few meters of the heavy duty trailer wire will even give you most of the colour code to make it easy to follow the diagram

Why do u need that many relays for standard headlights?

The 4 relay setup looks to be for minimal loss through the relays. 1 relay per beam per light. This also allows for plenty of headroom for upgraded globes.

yer thats what i thought 100watts will only draw 8 amps so as long as you get a 30 amp relay it will do both lights no dramas

Hi Fellas. Do away with guesswork. Relay size/lamp size is simple calculation. Wattage divided by Battery voltage = amps. Most alternators pump out 13.6v to 14.2v and a 12 volt battery fully charged = 2.2v per cell. 6 x 2.2 or 13.2 volts with ignition off. For example 4 lamps at 55w = 220 watts. 220w divided by 13.6v = 16.2 amps. One 20 amp relay will handle it although bigger is usually better. Hope this helps. Cheers, Derb.
