Wiring is not normal for tailights, common 12v (normally ground) , 2 grounds to activate (normally 12v)

 

Yes I am aware of that.
the problem is how to wire it properly.
most forums mention a-relay, but not all the same way to wire

 

Relay not required to add extra lights.
RZR 800 has constant 12v (+) common to both filaments of a dual filament bulb,
a separate constant ground (-) to tail lamp filament,
and a separate switched ground (-) ,from brake switch, to brake lamp filament.

The issue is some LEDS are polarity sensitive, incandescent filaments don't care about polarity.
You need to find non-polarity specific LEDs.

LED tail/brake light questions

I tried using LED in the tail lights of both my 800 & the 570. When I install regular 3157 Red LED, the only thing I get is a brake light on constant one way and nothing the other. Someone said that Polaris used CX sockets, so I bought a set of Red 3157CX LED. Installed one way and nothing...

Also a good idea to change stock bulbs to LEDs.
The incandescent bulbs are known to melt plastic sockets & tail light housings.

Absolutely. My 570 RZR melted the lenses and cooked/crumbled the bakelite sockets.
It turned out to be easier (and lots cheaper at the time) to change the bulbs. There's a lower wattage version of the bulb that is fine for tail/brake without blinding the person behind you and won't melt the lens/socket. Available any auto parts store.

 

That’s certainly interesting, and the bulbs themselves are an easy fix, but finding a non polarized LED light could be fun.
It is hard enough getting what you want at most parts stores when it’s something simple and you have all the information It will be fun getting these.
Have not seen lights listed anywhere before as being non polarized, but wasn’t really looking.

An easy fix I thought was getting a momentary switch powered separately and mount at the brake pedal arm.

 

You can use a relay and switch the ground, just as easy as you can switch the hot.

 

You say the tail lights work OK, but no brake lights . I had this when I changed my 2010 tail lights to LEDs.
Turned out the brake was working, just no change in the light intensity. The cure was to put a resister in the tail light ground wire.

 

How did you wire it up i tried that and it didnt fix my problem ?

 

Can barely remember, Don't think I changed any wiring, only added a resister on the negative side of the bulb.
