2 switches, 1 light question
Is it possible to wire 2 switches to 1 light?
I have flush mounted cubes mounted in my rear bumper, They are wired directly to my reverse light harness. Is it possible for me to wire a second switch to these lights that I can turn off and on as I needed?
I tried to look online for a diagram to do this but had no luck, was hoping i could find help here.
Thanks in advance

You could just use a 5 pin relay. By wiring the relay up to control the lights, you could splice your reverse lights into the normally closed contact on the relay, so when the switch is off the lights will come on with your reverse lights. When you switch them on manually the relay will close the normally open contact, powering on the lights. At the same time, the normally closed contact will open, preventing back feed into your reverse lights, eliminating the need for a diode.

A) "30" is connected directly to the battery
B) "85" is connected to a "Switch harness" and the power from the reverse lights
C) "86" is grounded
D) "87" is to the lights, which are grounded

do you have a drawing of your concept?

This is assuming you use appropriate fuses on the 12v power source, as well as probably a good idea on your R trigger
So just to make sure I get it right Patman

My numbers are ISO Standard relay callouts
30 should be ignition 12v (fused)
85 switched ignition 12v AND Reverse trigger with inline diode
86 ground
87 to lights

Basically you would wire it up as follows,
pin 30 to your cube lights
pin 87a to your reverse light trigger
pin 87 to switched/fused 12v feed
pin 86 to secondary switch
pin 85 to ground
by wiring as above your cube lights will come on with your reverse lights like they do now, and when you flip the switch you can power them on manually and not back feed your reverse lights.

Awesome! Thank you sir!

pins 30, 87, 87a are not polarity specific. You can send 12v dc thru them in either direction. They were designed to have pin 30 as input and 87, 87a as selectable outputs. But you can use it as a dual selectable input with a single output by using 87, 87a as inputs and 30 as output.
Now pins 85, 86 are polarity specific. If you feed dc current into the coil the wrong way, it will not move the contacts and nothing happens. so make sure you get the polarity correct on 85 and 86.
