Yes.
And with H3 bulbs, it would be wise to use a rely if using 3 or more lights on the same (standard plastic) switch.
I ran 4 H3 halogen rock lights through a nice big KC Highlights switch, and I melted and fried the switch!
So each bulb I am using is 55 watts, or at 14 volts, that would be almost 4 amps each. I was running 4 bulbs through the same switch, so 16 Amps was too much for one switch.
Now to compare this with these little LEDs that only draw 0.0038 amps each (0.023 amps / 6 LEDs), you could run 4,210 LEDs per switch before you melt it! WOW! Your entire truck would be glowing!! And that's only on one switch and one circuit!!
