What is the draw of the light bars ?

 

[Tinstar]

LEDs or Halogens?

A 70 amp relay will handle 70 amps but without knowing what the lights draw your guess is as good as mine!

Those LED light bars shouldn’t pull anywhere close to 70 amps.

This!

How many lights?
What kind of lights, incandescent or LED?

I cannot even imagine any light bar drawing 70 amps DC. I used to install light bars on cruisers and fire trucks and the largest relay I ever used was a 30 amp (black cube type) automotive relay to provide power to them,,, this was before LEDs took over the market.
