I want to string 2 sr2 10 inch bars together off one switch. They each came with a harness. If I string them together does each light need a relay, or can I just splice the wires next to each other on the same relay? I my question makes sense.

Thanks

Don't know all the details about the light's actual amp draw, but with LED's being so frugal, I would think one standard relay would run both with little issue.
Since they're commonly available in 30 and 40 amp ratings, most relays should handle both sets I would think.

Is there a specification for amps or watts with your lights?

Paul,

Here is the info.
Watts: 52.4
Amp Draw: 3.8
LED's: 15

I ended up putting in both relays and spliced them together on the switch side. Figured better play it safe.

Happy thanksgiving.
Chris

Nothing wrong with safe. But you can see by the light specs that even one light-duty version of the relays would handle two with no problem. So if you ever wear one out, or change your wiring up for any reason, one should do it.
The lightest I've seen is like 15 amps, and the lightest that you typically see available is 30. Almost four times the need. So you're certainly good with two.

And the benefit of two is that if one goes out, you don't lose all the lights.

Paul

Its funny, I used to wire fire trucks where the lightbar draw was over 80 amps. Now the entire rig runs about 12.
