Adding LED Lights to existing tractor wiring

[bedn0009]

GJ Experts,

I have a small John Deere garden tractor and I'd like to add some LED spotlights for plowing snow.

Would it work if I added 2 of these LED lights to the existing headlight wiring harness? For reference, my existing headlight bulbs are THESE.

This would allow me to switch on the new LED spotlights with the existing light switch....

Is there additional information you'd need to provide me with an accurate answer?

Thanks for your help

Depends on the ampacity of the switch, does it control the lights directly or through a relay? It is probably best to wire your new lights separately with a new circuit,switch and relay.

I used different lights but did pretty much the same thing with my ATV that I plow snow with. I can't think of a reason your case would be different. The factory lights did a real good job of lighting up the back side of the blade, and not much else.

I put 2 of those exact same Nilight 4" LED bulbs on the back of my tractor (put a 20" front facing on the ROPS.) I just went and put a meter on them and the little ones draw 1.25a each, so 2.5a per pair. Since you are already running LEDs headlights, you probably have plenty of circuit capacity left over what the original halogens pulled.

Thanks. Is the only thing that matters in this case amps and the associated fuse they're on? Some one else told me to also consider wire gauge, which I believe is 16

current/amps yeah, that's the main thing. 16ga should be good for 13a. Like a chain, the weakest point of the circuit will cause the issue. The switch is "probably" a 20a switch, you can probably pop it out and see the model number and pop it into google to see the specs.
One of the reviews on your headlight bulb says they draw a lot less than 100w, but don't state the measured value.
At 1.25a and 12v, those little 4" bulbs are only adding 15w each, 30w per pair.

What's the factory fuse value for that headlight circuit?
