Is there a circuit to control the DRL?
Here T1 and the associated parts perform the same function as above while T2 is rigged to produce 50% less voltage for the DrL when the headlights or the turn signals are switched ON. The last circuit is also a smart way of controlling the DRL illumination.
What is a DRL or day time running light device?
What’s a DRL or Day Time Running Light Device: A DRL is a safety car lighting device specifically assigned to moving vehicles for increasing the conspicuity of the vehicle during day time, especially when the daylight is accompanied with fog or during dull overcast days.It is normally fixed just beside the headlamps on either sides.
When does the DRL need to be triggered?
You are right, the +12V needs to come from the ignition feed, meaning only when the ignition is switched ON, the DRL and the associated circuitry should be triggered ON for the required operations.So the modification will be simple, instead of connecting the +12V to the battery we can integrate it with the ignition 12V feed.
Can a DRL module be connected to a fog light circuit?
the Porsche 987 and 997 Bumper Lights only the parking lights are CanBus controlled , in this case the DRL Module cannot be plugged to the parking light circuit for DRL function. On the other hand the Fog Light circuit is not controlled by CanBus therefor there is no problem to connect the DRL Module to the fog light circuit.
