Morning all,
Anyone have a simple schematic for wiring up daytime running lights (DRL's)? Being in Canada where they have been a requirement for many years, I've noticed that I'm considerably less noticed without them. I know some cars ie. Nissan, had DRL's which operated the High beams at 50% power.

Why not merely drive with the low beams on?


Running the highs at 50% ? A bit wasteful to me. I don't get the logic?
And a resistor? Merely converts volts to heat?


Just me, musing .

I want DRLs myself; perfectly doable. A project a bit further down on my to-do list.

I'm not aware of anyone already having done the job and having a schematic to share, though.

Cheers

Start at a white ignition power wire. Use it as trigger for a relay. Oher leg to brown, always hot. Another color for the other leg to the low beam sockets.


Sophistication A delay relay. Lights remain on post shut down for a short interval!


Voila, ignition on, lows on!


Me, no. If desirable, a darkish day or in the rain, just turn the knb1


Caveat, do not leave it turned when parked.

Good call Carl. Been there before

That's pretty much it, Carl.

If desired a person could design the circuit so the DRLs don't operate with the handbrake on or other pre-conditions so that the DRLs don't operate when not needed.

Thanks everyone,
Looks like a winter design project - on top of all the others!
