marker lights

Due to a deal I found on ebay I have a ton of marker lights I bought for my 53' drop deck race car hauler.I am wanting to put about 70 non led marker lights on it and am wondering how many circuits I should add.The tractor has about 48 non led marker lights on one circuit but they could probably be brighter if I added a second one to them.

Anyway back to the trailer. I planned on leaving the tailights on there own circuit.I was going to put the marker lights on the tail on the interupted circuit. That leaves about 50 amber marker lights on the front and the sides I have to power. I planned on running 2 circuits with 25 lights each on those circuits. The lights are the double bulls eyes with the two mini bulbs in them. I was hoping someone could tell me if that will work alright or if that will still be to many per circuit. I would appreciate any advise or ideas on the project.

Tractor is an 04 Western Star and trailer is an 86 Manac.

Thanks in advance,
Chad

 

I appreciate your input as for the alternator it has a fairly large one on it that doesnt have to work to hard keeping the batteries charged up with the fridge running and the lights on the truck.I pull a flatbed during the week and the racecar trailer will only be used on the weekends and the lights will only be on during the trip home from the races.
