Hi Robert Thank you very much! I took the lenses off and saw some jacked up wiring. One of the red leads was actually grounded. I see on the terminal, #2 goes to the rotators and #4 goes to the wig wags. I may run a jumper between the two. I bought a 50 amp power supply to run it. Take care and thanks for writing!

Maybe grounded internally. Most all lightbars come with an external ground due to the mounting (clamps not bolted) Those older bars many times had 2 hot leads due to their high current draw. Most of the bulbs are 50 watts, 4 amps per bulb. Many had been modified by the departments or persons that used them. I donated one to the Richmond TX police department BBQ team. My Nephew is a Richmond PD officer I installed a power supply in the bar, it had a power cord exit the bottom and you just plugged it in. If you just want the effect you can replace the bulbs with lower watt bulbs. May require you to remove the lens and check the connections. If you still cannot figure it out, I can arrange a time to look at it.

I installed many back in the day when all I did was Fire & Police installs. Due note they require upwards to 30 a to power them. Is the pigtail still out the bottom of the bar? If so, how many conductors is it? These bars were ordered with many configurations, Take-down lights alley lights, an such. Most had a ground and each wire controlled each light. Many also had a siren speaker wiring.
