I have a Kensun Xenon kit installed and working really great.
In my country, run with low beams on is mandatory 24 hours.
I have the DRL function on, since it is great to get the low beams on when the car is on, without getting dashboard lights nor position lights on.
I know it is not recommended to start the vehicle with the lights switch in on position, due the high consumption they have while starting up, but if you have the DRL function activated, that is what will happen.
One out of three times, one of the low beams lights doesn't turn on when the vehicle is turned on (sometimes it is the light on the right, sometimes it is the light on the left, it is not a bulb o ballast issue, I think), so I have to flash the high beams a couple of times, until it turns on (it's a trick I discovered).
The other way to get the low beams on without problems, is to get the car with ignition on before starting the car.

My question is: is a bad idea to put the vehicle in ignition ON (pressing the start button twice) to turn on the lights and immediately start the vehicle?
Could it damage something electrical in the vehicle when it is turned in this way?

It's what I've been doing for the last few days to avoid this issue with DRL lights ...

 

no problem at all. This is a simple way to get things powered up otherwise the voltage sag caused by the starter motor can make some devices not turn on properly. I always turn ignition on (press the start button with foot off the clutch) before starting the engine so my temp gauge powers up reliably.

 

squawSkiBum, thank you very much for your answer

 

I was checking on Amazon/eBay that there is a 12V timer relay so you can configure the delay time for the headlights to be on after car starts (ignition on).
I can´t imagine how can I use it since I was totally sure that there was a headlight relay on the engine bay relay/fuses box but there is only 1 fuse for the headlights line.
It seems I should to use some logical board with a time relay included to be added to the headlight fuse...

 

I could see on eBay, Amazon and ohers that I could use a timer relay on the headlights.
I was sure that in the relay box (engine bay) there was a relay for the headlight but not, there is only one fuse for it.

Has anyone used a fuse with relay included or made any modification of this type?

I don't intend major modifications, just replace the fuse with a device that fulfills this function or replace the existing relay that I have not been able to find to.
I researched and saw that through NCS Expert it is not possible to generate this delay from the configuration itself
