Then wire the light bar on the rack to the high beam wires. So with lights on in low, flood pods are on. With lights on in high, both flood pods and light bar are on.

I'm blind as a bat. I like lots of lights so I can see where I'm going.
That is a really good idea!

One question. If i do decide to (later) put a light bar on the front, how do i wire it to the rear tail light?
I was under the impression the tail light is only 5w max output. How can i wire a 50W light bar to the 5W tail light without blowing the fuses?

Update.

So the cheap led bulbs i bought to replace indicator and rear light fit and work.

Haven't gotten. Green ones in yet, so the neutral light is stock, and reverse is led.

Camera struggled with glare. IRL, the led is about 2.5x brighter than stock at about 1/2 the wattage of a stock bulb.

Also, as promised, here is a photo of my retrofit 18w led floodlight headlights at late dusk.

Much better than stock.

Use a relay. It basically is a giant switch that takes the load off of your electrical system.

You use the tail light wire as the trigger wire for the relay. The actual power goes from battery to relay, and then from relay to lightbar. When the signal wire (tail light) gets 12V, the relay activates and sends power straight from battery to lightbar.

Thanks for the explanation.

Wouldn't a 50w light bar + 5w tail light + 36w front lights overload the atv's charging capacity?

Because i do tend to plow at night on my old atv.

So wouldent having all those lights on (91w total) + running a winch drain the battery or put too much strain on the alternator?

LED's draw MUCH less power than your factory headlights. You can't really go by W, you need to look at the Amp draw. Most of the cheap LED light bar ratings are BS anyway.

For example, this one only put out 84W for one person, drawing 6.9 amps, but it's advertised as 120W. I have one like this on the front of a 350 Rancher. Puts out plenty of light, and I've never had problems with it running down the battery.

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

That said, a 50W light bar wouldn't draw much at all.

I don't think you'll have to worry about the lights for normal use. For plowing you'll likely run into issues from running the winch. They draw a LOT of power.

You might rig up a 2nd battery in a battery box to use when plowing. Strap it to the rear rack.

What is the total output charging capacity of the stater in a 1944 trx300FW in watts/amps?

Curious for future changes just how far I can push lighting (or other accessories) before I am draining more than I am charging under normal driving conditions (not all out).

Cheers jeepwm69. Lots of good info.

LOL, back then they were still using 6 volt systems and generators.

Looks like .22/KW at 5000 RPM's from the FSM.

From a calculator of KW to amps I found with a google search that's about 18.33 amps

My Foreman 500 shows .326/KW at 5000 RPM's, for comparison's sake.

@retro can probably better explain electrical stuff. I know just enough to be wrong and shock myself often.
