installing whelen car strobe lights.the directions say to wire the power to the battery with wire that can hold 125% of the power
Go with a guage bigger than the wire harness on the strobe. If you go too small of a wire it could put too much of a load on the wire. That will cause it to heat up and can catch fire if it gets hot enough. Like what sparky said, use a relay. I installed neons and strobes in my car using 10ga wire relays, and a power distribution block.
even speaker wire can handle 12V of power direct to the battery as long as there is some sort of fuse in the setup and you are properly grounded
use one that is larger than what is used going to the strobes. the less the resistance the better and brighter the strobes will perform. and it is a good idea to ues a relay.
Use 12 Ga. wire. However, do not wire directly to the battery, use a relay.
