So this thread may not make any sense whatsoever as I have no idea what I am talking about. I recently purchased halo's and am in the process of having my friend install them for me and I think what we are trying to figure out is which circuit you should use run lights that you want on when you turn the truck on. That is exactly how he worded it to me through text.

Perhaps someone who has halo's could enlighten me on how you went about the wiring? Thanks a lot.

 

You generally want those to come on with the parking lights (the first selection on your headlight switch). Turn on your parking lights, find which bulbs light up, find what wire going to the socket for that bulb has power, splice into that wire. Most halos are LED so they dont draw enough current to worry about putting in a larger fuse.

good luck

 

to comment on the post above me... even if it wasnt led, you wouldnt want to up the amps for the fuse. that wire is only rated for so much power and is fused accordingly, thats pretty risky to up the fuse and forget about the wire carrying the power.

but ya hes right, tap into the parking light wire. if it were me i would fuse that wire too. just throw an inline fuse in there. it will protect your fancy expensive halo lights against any shorts, and your stock parking lights.

 

Use the parking light only to switch on a relay which should have its own power from battery.
Go from battery to relay / relay to lights and parking lights to relay to tell it when to turn on.
Run and inline fuze

 

Theres no reason to run a relay for a circuit that draws such a miniscule current. Most standard LED's in things like halos are 1/5 watt to 1/3 watt. most only have 2 per halo, assuming 8 total. Thats only 1.6-2.6 watts for the entire system. on a 12V system thats only so at the most you have .21 amps. Even if it has twice the number of LEDs thats still only .42 amps.

 

Ok guys I sent him the thread and his main question is.

The thing is
Your drl is your high beam but half the power
So does that make the halos "half" as bright?


Thanks for all of your input by the way!

TTT. Just looking for reassurance before we go ahead and give er. Wire to the parking lights is correct?

 

Wait, you have DRL's?

No, they will not be half as bright, because you are running the halos off of the parking lights, which are a separate circuit from any of the headlights.
