Uprated light looms

What amp wire are you using from the relay to the lights?

 

you can work out stuff like that by...watts diveded by volts..watts being both the bulbs and volts being 12v..always round it up rather than down

 

that works out as 9v cable, cause i'm doing a relay for each light with them being rallye lamps, so 4 relays.

Ta Pigbladder, i didn't know about that Big help!!

with each 65watt bulb feed, that to each wire, you would need a at lest a 5 amp wire, I would use 8 amp


as pigbladder says watts divided by Volts

so 55W 13.5 volts(12.5 when engine not running )
would be 4.07amps

100W would be 7.5amps, but always remember to use larger wire than required, current causing heat transfer & underpowering the unit,

so two power cables to most H4 bulbs, but remember to have the same wire for the earth!!

Hope that help, at little

 

Ive used 17.5 amp wire and same for ground ---- 2 relays in total and wired so dipped beam stays on when full beam is on

Also Rallye dipped beam takes an H2 bulb but not sure about the full beam -- Its a single filament bulb not double filament so it aint H4

 

It uses H1 main beam, all sorted now, used 27amp cabling, i hope thats ok?

 

Cable is fine - make sure that its all fused etc

 

20amp fuse 3inches from the battery on all the relay feeds.

 

sounds good, i'm using 18A cable and the lights are on separate relays, should be plenty methinks. only problem is the bundle of wires and relays you have to try and hide!

 

bah, hiding them is the cowards way out
