Help with headlight upgrade.

Post by Wozza244 »

This pic i have found, it dont look right to me, will this give me the extra power im losing through resistance?

Or shouldd i just use the high and low beam wires as switches for the relays and run wires back to the lights from the relays.

Eg. 2 relays per light?
Sounds like overkill

These days I would

a) Upgrade to HID (35w = 2.5A and more light)

b) Upgrade to 55w +50's (white, not blue) (55w = 3.5A and more light)

c) Re-do the wiring as a last resort. I have done it too many times. A & B are better options.

You need at minimum
a) A relay for on / off
b) A relay for high / low
Many people want to run seperate fuses like OEM, and that needs 3 relays.

I just did this setup a bit different than pictured, my old low beam wire became the switch for the relay and now i have 50% brighter lights!
If i was to use the same relay to do this with the high beam, i would have to run a diode so the power from the high beam would not go back through the low beam wire, if you get what i mean.

I have 2 HID spotties and a hella 4000 for high beam so im not gonna bother.

All is good!!

I did mine with 2 40 amp 5 pin relays
A 10 fuse holder (25amps per fuse rated)
2 new H4 plugs, (some twat bodged the originals)

pretty simple, use the original wiring on the drivers side to trigger the relays, mount fuse holder next to the battery and run power from the battery to the fuses to the relays.

twin core to the headlights and new clean ground for the headlights back to the battery.

about 20mins work.

got better light from that wiring with standard globs, than i did with standard wiring and 50/100 globs

but if you can afford HID that would work.
