Add lights to a 641?

Hi I have a 1958 641, 6 volt. I got the front headlights to work, and would like to add two lights to the back (attached link, looks like 6 amps each). Also, I probably don"t need the red tail light.

Question is, how much amperage can I have on that line. I took out the buss fuse, near the OEM light switch. Looks like it says 30 amps.

New 14 gauge wiring.

Can I have total four lights, the headlights plus two more @ 6amps each?

I have a red tail light because I have to travel a 1/2 mile on the highway from my woodlot.At 24 amps you are drawing more than the generator is rated for.14 wire is a bit light for 24 amps.Your generator is rated at 20 amps so 4 lights is more than the generator can handle.I have a seperate switch for my rear work light.I used to come out of the wood lot at dusk but quit earlier now. Still use the lights because stupid drivers dont know Im going 10 mph.Im putting an SMV on my wood trailer today.
 
you COULD run it.. I'd run a seperate wire circuit for the back. the problem is you will almost assuredly be in a discharge situation with all 4 burning, and running.

for short time period.. ok.. but for extended it will overheat that generator... and that's when run at rated rpm to actually get that wattage / amperage out of it. running at lower throttle you will reduce genny load.. make it happier.. but will also be discharging the battery slowly.

COULD do that. IE.. idle down to 15a draw to keep genny happy for long term.. and be discharging.. then before shutdown, kill rear lamps and throttle up to rated rppm and run around for another 20-30 minutes to recharge storage cell.
 
Thanks to all for the thoughtful replies.

Probably the long term solution would be to convert to 12v, but I was hoping to see how it goes this winter.

I bought a King Kutter 7' blade a few months ago, got some weights as well. Want to see how it moves the snow and slush. The driveway is about 500 feet total. But I am on a county road, so the lights seem to be a good idea, more the better.
