Why not this... This is what I am planning for my car (I don't think I will use the "indicator off" feature though)

I just like the idea of having the relays operate the lights and having all the relays in a central location.

DesertGuy given the caliber of your car i know that the quality and wattage of the lights you will install and there won't be anything that you would be able to run thru a switch the idea behind my response was to demonstrate a basic current calculating exercise and to make people aware that in low wattage situations a simple switch can still be used

but by and far the better installs utilize a relay setup

Hey Bob, don't blame me... I learned the above from you

Thanks for the help, BTW

And you you learned your lesson well grasshopper..... now if you could only teach this dumb old fart how to make these cool diagrams

TO RELAY OR NOT TO RELAY

Recently I purchased alot of these switches; they are a triple sealed, o-ring toggle switch rated to 20A. The Bosch relay commonly used is rated to 30A, from what I see. Considering the following:

2 100W Off-Road lights = 200W
200W/12V = 16.66A

Would you use a relay or simply run it through the switch? Is there any benefit one way or the other? I understand running through a relay for a lower rated toggle, but would it be better to K.I.S.S in this case?

those appear to to be a pretty stout looking switch i might be tempted to try running the lights directly thru those switches just to see how they stand up but they i am always curious about things like that
