I have some LED 9005 in the high beams. I have some resistors JnC made me up so I can get them to work with no CEL.

I put my multimeter on the high beam socket when drl should be on and I get 2.5 - 3.0v.

I want to use a relay to power the DRL so I get the full 12v going to them.

my relay, and most I have seen, need about 9v to trigger.



so




how do I make the 2.5v trip the 12v relay.

 

measure the voltage after flicking the high beam switch on?

 

yeah. the high beams trip the relay and it all works fine cause its 12v.

the drl voltage will not.......SO

what do I do to rectify that LOL


i have a voltage regulator that I can trip with a 9 volt and a 6 volt battery . thats all i can test on my BENCH so tomorrow I will see if the drl signal trips that regualtor. it will max out at 10 volts but thats better than 3

 

your relay will chatter, DRL is a 12V PWM signal that your meter will read 2.5-3V average. Straight 12VDC high beam

 

i get that.


so will this work to make the 3v look like 12v to the relay: http://www.electro-tech-online.com/e...v-project.html

 

what i was saying was why not just leave your highbeams on, and that'll be your DRL, at 12 full volts

 

Oh. Lol.


That's too easy. And I would have to remember to turn them.

 

pyro,

i gotr my new bulbs today.....the cree with the smt around it.



so I tried to put just my high beams on and it wouldnt work. I can get them to 'flash to pass' but when i push it the other direction (fwd) for lock in high beam the high beam dont come on UNLESS my lights are on.

i didnt try auto.....in daylight.....i will do that tomorrow if the sun is out....cloudy and rain coming now/


do yours?
