I googled this circuit the whole Internet and not found how to do it, and finally got a simple circuit, and would like to help you

Step 1: What You Will Need !!

  1. 1n4007 Diode
  2. 5 pin car relay
  3. Capacitors 6,600uf (minimum), I used 3 of 2,200 microfarad
  4. wires
  5. led drl for test
  6. soldering iron
  7. electronic skills

Step 2: Solder the Capacitors

solder the capacitor terminals in parallel, positive with positive and negative with negative like the image

Step 3: Connecting on Relay

connect the negative of the capacitor on pin 85 of relay, and the positive on pin 86

Step 4: Positive to Drl

connect the pin 87a on the positive DRL and pin 30 to the positive battery, connect the pin 85 to the negative batery too together with the capacitors like the image

Step 5: Diode

connect the 1n4007 diode on pin 86, as in the picture (the negative side of the pin 86) and connect the other end to the positive turn signal wire

Step 6: You Finished !!!

check out the links are correct, any questions do not hesitate to ask !!!! very simple ...

<p>Could this be used to turn off a headlight while the turn signal is activated?</p>
Belo circuito Renan, parab&eacute;ns, vc pode me ajudar a montar? Qual rele usado entre outros.
Would the capacitance change depending on the type or number of LEDs ?? ?
<p>it does not change, just to keep the relay activated while the turn signal is active, not to blink the two colors together</p>
<p>Nice control circuit. Also great first Instructable. Very well written.</p>
<p>thank you !!!</p>
