Upgrading Hi-beam Globe On S2

[DaveB]

Hmm doesn't make sense imo for Nissan to put the switch on the wrong side of the relay though! (but I've seen it elsewhere in the stagea when wiring the alarm). You've got it right though I think, as of course I should have read the diagram fully in the first place... the high-beam globes are indeed sunk via the switch matrix. Damn. I'm sure there must be a good reason for this, but I just hate it when they put the switch on the high-current side of the relay, because it means the switch can burn out and the brilliance of your lights is potentially affected by the condition of the contacts in the switch. So yeah, another relay is needed, probably easiest to install directly at the high-beam units.

yeah, i'd think the +ve feed wires to the high beams would be able to take the higher wattage globes, its just running more amps through the switch that would bother me.

i would install another relay that is switched by the high beam switches -ve feed, and have it switch a good ground to the globe. if you know what i mean. that way you dont have the increased current running throught the high beam switch.

Exactly. I was thinking of lifting/cutting both connections at the high-beam unit, and effectively making them the new connections to the coil on a new relay. But if you wanted to only lift one and run the higher current through the existing HID/Hi-beam relay, then yes it makes sense that the negative connection must be the one switched by the new relay, otherwise you will just end up with more current going through the indicator stalk :S

PS now that I look at that diagram again, it appears that the two (top/+ve) connections are marked "Hi", as the low-beam ones are marked "Lo"... I just drew my circle over them lol.
