Use relays for Leds?

[CJL 10+ year member]

Seeing as LEDs pulls mA of power, Would I still have to use relays?

For example ,if I wanted to tap into headlight switch,couldnt I just wire it up raw?

I would fuse, but no need for a relay unless you're using an ungodly amount.

What size fuse does somebody normally run?

It's going to depend on how much you're drawing. For small electronics I usually just stick in a 3amp.

it depends what you're drawing power from. If it's an accessory wire, chances are it's already fused. If connected straight to the battery with no fuse, asking for a problem.

in this case hooking up to a headlight switch I would be absolutely sure to fuse. better safe than sorry. Seriously, how much work is it? all you need is a fuse and 2 speaker clips and you're golden.
