What switch type?

[slowneasy]

What electrical type switch do I need for my aftermarket back-up lights so I can have them to come on only while in reverse, not at all, or just to work at night/hook up a trailer? DPST? DPDT?

Thanks!

That's a similar question I posted on a forum for relay questions. I dont know if it will help you much since you dont want them to come on at all in certain instances.

on off on switch... . and 2 relays depending on how big the lights are...

I had an older White Nite backup light system that I gutted. I used the relay and on off on switch mounted in a weatherproof single pole pvc electrical box and blank cover. I mounted this to the round receiver hitch under the rear bumper. I have a relay up front controlled by a switch that powers the backup lights when the switch in the rear is in the on position and I select reverse.

When I want light in the back when I'm not in reverse, I flip the switch to the other on position.



DF5152 is correct. You'll need 2 relays and a switch, or 2 switches if you don't want the lights to come on every time you are in reverse.

I used a single relay and an on- off- on switch.



Switch up, works with factory lights.

Switch off, it's off.

Switch down, manual control. This would normally turn on the factory reverse lights, but a little diode stops that!!

Thanks everyone for the replies! Fishin' Guides post is what I'm wanting to do, however, I am using a lighted SPST on-off-on switch and it stays lite in the off position. Do I have that wire hooked up wrong? BTW the switch is a Contura Rocker from Waytek. There's not a wiring diagram with the switch only tiny numbers by each termial. If I have it wired incorrect, could someone help me out with which wire to each termial?



Thanks again

try switching the wire on the back of the switch

what diode did you use (link?) I've looked all over for a diode that can stand up to the temperatures under the hood of our trucks and havent found one with a satisfactory spec sheet that I can tell.

SPDT Center off. One common 12v+ and 2 switch legs, 1 switch leg to each relay coil.

I'll have to get the part number. I am on the road this week and don't have access to all that info. FWIW, I put the diode in the cab.

I used this wiring diagram for my backup lights. The backup lights come on in reverse, I have a switch in the bed and I am planning on adding one in the cab. Not exactly what you are after but ti does show how the diodes are wired in.

I used a DTDT switch (it is lighted as well) and a single relay to run 2 55watt B/U lights. It is what you are looking to do. There is a wiring Diagram in my RR. It is the simplest way to do what you want that I have found. I think it used the least amount of wires. I tap the reverse "trigger" wire from the transmission and run that up to the relay on the firewall. That way you don't have to runa wire from trailer plug all the way up the frame rail.

I like to keep things simple



Edit here is my pic, little hard to read though
