Well wired up 2 55watt Hella lights to a 20amp switch an put a 15amp inline fuse in place but noticed the switch is warm after running them for a while. Are relays needed or is it normal for the switch to get warm. Im only drawing 9.96amps combined so figured a 20amp switch would be a lil over kill. What do yall think? Btw I run them when ever my headlights are on.

 

I would. Can't hurt.

 

Do the relays.

 

Will do had me worried when the switch got warm. Is it normal for the switch to get warm with out relays?

 

Yes. The factory headlight switch melts all the time.

Those switches aren't meant to pull that much.

Where did you get that you're drawing 9.96 amps from?

 

I never trust switches.

Always use relays on any sort of lighting.

 

55x2=110 110/12=roughly 9.96

 

Probably woulda been the smart thing to do but Im very impatient lol

 

Relays allow you to control a large load (amps) with a smaller load. they will protect your electrical system from overloads and in many cases keep you from melting an entire harness.

Use 'em.

 

Gotcha good to know

 

It is NOT normal for a switch to get warm.

And, using relays is ALWAYS a good idea - even if the switch can handle the current, running full current from the battery, to the switch, to the consumer is an inefficient way to go about it - using a relay allows a much shorter full-power path, and therefore significantly reduced conductor loss.
