Wiring DRLs

very attractive!

 

I used a fuse tap and a relay to get power for my LED foglights used as DRLs directly from the fusebox.

Used the 12v constant on/hot terminal for power. Tapped one of the 5amp fuses in the front right row of the fusebox to trigger the relay in Ready Mode, I think it's the inverter pump fuse, or something like that.

I bought these for my 2012 v Five, then removed them, relying instead on an 'on when +12.8V' relay powering much brighter yellow LEDs with white halos replacing the fogs.

 

Here's where the constant 12v on/hot open terminals are at the back of the fusebox, the ones with the red wires going to them. They take regular 1/4 inch push on terminals.

Who sells an “on when 12.8v relay”? This is the closest thing I’ve found:

Nothing appears in your post, but look for a voltage sensitive relay (VSR) or module. Should stay open at resting battery voltage, close when alternator kicks voltage up.

This item is similar to what I installed on the fleet, years ago:

What looks like a random ad in my post is actually a link I posted to an Amazon item.

 

So random that nothing appeared!

 

trying again

The one @Air_Boss linked would be better.

Same idea, but why not keep it simple?

 

So I do have these on my Prius but I'd like to turn them on with the headlights, is that possible?

DRLs with headlights as well as independently? If they are always on, they are on with headlights.
