(I saw a lot of reads on this, but no reply, so I'm adding this note: I've got a question / suggestion requests on how to best wire this up
. See below)
I'm tired of surprises from the wildlife around here, so I decided to add lighting. I've now got a 23" LED light bar that I just mounted in the bumper lower air intake of our 15 mada.
So nice of Nissan to have put 3 pin clips there (one centered, other 2 19 inches apart) which made mounting of this bar (which has 2 adjustable sliding mounts) a cinch after removing the front grille (just clips).
My wiring plan is as follows:
1. Hot from battery to Relay #1
(with a 30A fuse between them) so the bar has it's own power and isn't sharing
2. Relay #1
controlled by tapping into the power going to one of the brights bulb
3. Relay 1 sends power to Relay #2
(maybe with another 30A fuse - necessary? recommended?)
4. Relay #2
controlled by in cabin switch (which will be connected to 12v in cabin)
5. Relay #2
sends power to the bar
This way the LED bar cannot be on unless the brights are on AND the in cabin separate switch is on. Turning off the brights will automatically turn off the LED bar which makes turning it off quick and safe when necessary - no fiddling for a switch. When on road, the in cabin switch can remain off for normal use of the brights.
1) I don't mind having 2 relays, but am all ears if there's a better way to wire this up. My only requirements are a) safety and b) having the bar turn on and off with the brights with an override off switch
2) I'll likely tap into the bright's power line using a T splicer since there's just not any excess wiring (and it's easy). Does anyone know what gauge wire feeds the high beam bulb?
