Lightbulb Help with light bar install

I am attempting to install a light bar on my sleds. They are both Polaris Indyís gen 2 I believe. No battery, and I assume no dc current anywhere to power the light bar, I am thinking of using one of the ac current wires from one of the headlights, and using a ac to dc rectifier then connecting that to the light bar. Does anybody know if this will work? Also could I use one of the high beam wires so when I use the high beam switch it will turn on? Would I need a capacitor/battery? I really want to do this and I donít have much experience with this kind of stuff. I just tried to read up on other threads as much as I could. Any help or advice would be greatly appreciated, thanks.

All of the lights on your sled are 12V DC. The ideal thing would be that your sled had electric start. You could hook the lights up to the battery with a relay hooked up to high beam circuit to turn on the relay when you flip the high beams on.

Depending on the draw of the bar, I am guessing it is a LED, you could power it off the headlight circuit. The headlight wires may not be able to handle the extra draw of power and melt. It may also tax the voltage regulator with the extra draw. That is the worse case scenario. LED's do not draw as much power as filament bulbs, so you should be OK. Do not cut wires and put in butt splices. Go to the harness plugs, pull the pins out and open the pin. Put your bar wire in and put it back together. This will give you a good connection.

Hopefully someone that has tried this will give some more information.

Thanks for the info, are you sure the headlights are dc? And just curious as to why I canít splice and use butt connectors. Thanks again.

Yes, your lighting system on your sled is DC. AC is used in your house.

You can use butt connectors. I just like to make sure connections are bomb proof. Make sure you use a good crimper, not the junk ones that come with those cheap kits you get at Wal Mart.

All the current lighting in your sled is incandescent, and it doesn't "care" whether the power is AC or DC. All the electronics on a sled are 12VAC unless/until you get into EFI components or starting/charging systems, which have a rectifier/voltage regulator (I think usually internal to the ECU on newer EFI systems). I haven't ever experimented with LED lighting on sleds, but I've heard some setups need a rectifier or you'll get low or no light output. So you may have to add that somewhere, but the power draw should be significantly less than the current lights.

Yeah I just ordered the lights, some wire, good butt connectors, and ac to dc rectifiers hopefully it works out Iíll let you know how it goes thanks for all the help.

I just did LED pods on a Yamaha Excel. Pretty simple. I cut the low beam hot wire and wyed into the headlight ground. The hot and ground are fed through a bridge rectifier and then the DC output is wyed off to the pods. It works awesome. Super bright. It would be more optimal if there was a capacitor in parallel on the DC side, but I couldn't readily obtain a robust cap that would be good across wide temperature ranges.

You just have to build some kind of harness to hold stuff. Cloth zip ties or whatever. Support the rectifier, wires, and connections. Tape all connections and exposed metal well. Oh, and use a fuse inline on the AC hot. Maybe 7.5A.

Well, I tried doing it and it didn’t go very well. I connected the power source to the rectifier to the light bar and I can’t get it to emit any light. I also tried without the rectifier no light whatsoever. Im gonna try to get my hands on a multimeter to see if I even have power going to it. Also I noticed all 3 of my bulbs were blown.
