LED windshield spotlight wiring

WHat's up all.

I am interested in upgrading my windshield mounted standard spotlights to LED. CUrious about wiring of LED's. They are 3x3 18W.

They will be wired to a switch (obviously), i will be utilizing a fuse, but is a relay really necessary for such low draw?

Thanks in advance

No. Especially if you are using a quality switch like a ARB/Carling

Your draw is 3 amps.

I have been using these switches. They have been reliable even with heavy sand and dust. I recommend them.

I picked up a set of those lights and was surprised how bright they were.
I'll use a switch up to half of it's rating.

Maybe it's just me but I find that mounting lights on the windshield to be a completely useless endeavor. Even the old school kc anti glare cups still didn't convince me it was a good idea.

Mine are indispensable. I need to see clearly for a quartermile+, top of the windshield is the only way.

Get em' up high and away from the hood and aim them carefully. I found mounting them to the hinges useless. took them off in 24 hours.
I have a set low in front that take care of close duty, and more than a set above the windshield lighting up a solid half mile.

I'm fine with above the windshield. I have low gloss paint on the hood and my led bar above the windshield to reduce glare. However I had a set of piaa's on the windshield hinges and they were terrible. My buddy has them now. He hasn't used them yet.

Got it.

Low gloss here too.
After one outing , the lights were off the hinges. So yes...
Worst place for lights ever.

i would wire up almost everything thru a relay....and I would upgrade the power wires one wire size, to the lights and 'devices'...

I would keep the relays out in the engine bay, all located centrally/together... seems to make things cleaner and easier to troubleshoot

You said you are upgrading your lights to LED. If the relay system is already there for the previous lights, why not use it for LEDs?

I suppose i was indirectly inquiring whether it 'could' be used and also whether it 'should' be used. Thanks all for the clarification. This will make install simple.

To anti and chris.... i have a glossed hood, but not too much glare off it at all. I'll try and dig up some pics. I don't wheel at night (aside from camping and trail rides with the wife). I will NEVER use them on the road (even though for the most part its tolerated up here in Canadia)

currently?

or which LEDs am i replacing them with?

spot style (thin narrow far-sighted beam), yellow lens, 150W snappy lights (ebay). FOr the price they did what i needed them to and far better than expected. But as i continue to work on my rig and build it up, so-to-speak, my needs are growing with its capabilities. Hence, LED. (just too efficient and sleek to say no). But also, as Chris will point out - the housing of the older style spotlight is just too large for the windshield hinge, it does create blind spots.

I am mounting the removed spots close together in the center of my bumper. Just going to weld a couple tabs with pre-drilled holes in it. Then i'll have used all my switches up in the cab and I'll have a pretty good amount of light (more then i need which is always good). On the plus side, the yellow lens with the smoked baffles on the Black Magic Hella 500s already installed on the bumper go well with the black and yellow motif of the heep.
