Wiring daytime running lights with a relay
Anybody know how to do this without one of those kits? I have tried several combinations on three different relays to get the low beams to come on
when the car has power to the fuel pump, whilst allowing them to be switched on for high beams, and nothing seems to work. Is it possible that all
these relays are broken?
I had thought about just using LED's on all the time, but I already wired in a pair of round ones for position lights. I guess you can have them
serve two purposes can't you?
Thanks!

Have you tried taking your power from a switched live on your ignition (a good live that isn't permanently live) to your relay? - you could
always borrow the relay from your tintop to check if it's the relay? 4 way relays are pretty standard

I would have though you could just take power
from the heavy wire from the ignition,
(Black/Blue If I remember correctly)
Then you wouldn't need a relay
FREE THE ROADSTER ONE…!!

DRLs are legally required to go on when the engine is running and off when the head lights are switched on .
To do anything else is asking to get pulled over, also keep in mind as DRL are about to become a legal requirement for new car in due course as an
obligatory light they will become part of the MOT test.

Can't you just use a standard 85/86/87/30 relay. Ignition live to 85 and earth 86 through the side lights. Battery live to 87 and connect 30 to
dip bulbs. When ignition is on it will earth through the side lights enough to switch the relay but not illuminate the side lights but will switch on
the dipped lights. Rear lights will not illuminate. As soon as the side lights are turned on you will have 12v on both sides of the relay switching
circuit and the relay will switch off.

What are side lights? It's not a term I know. Do you mean position lights?
I am encountering no success and am more confused than ever. Thanks anyways.

Sorry bout the cultural difference there. Side lights = two white lights on the front and two red lights on the rear. Not on the sides of the car at
all. I guess you could call them position lights. They tend to be wired to come on with the first position of the light switch. The second position of
the light switch keeps them on and also brings on the head lights which actually help you see where you are going. A separate switch then changes
between high/main beam and low/dip beam.
So yes probably position lights.
My suggested circuit will give automatic dip/low beam when ignition is on in the day time without the position lights showing any light. Then when you
switch on the cars lights at night the relay will cut out and you can have just position lights or high or low beam.

Thanks for that!
I have rewired so that the Position Lights, are now beehive lights mounted under the headlights, a la Caterham, and LED's are now going to be
the daytime running lights. I have separate indicator lights. Yes, it is a bit crowded up there!
Now, I have a normally open switch that closes when the handbrake is pulled. (earthed) How can that be made to work so that the handle down position
is allowing the LED's to come on? I have several relays I can use, but am not sure if they are needed.
