Is it technically possible to make the Grande Punto full beams and dipped beams both be simultaneously lit together?

Yes.

How can I do this? Will I a need relay harness?

Technically but a really stupid thing to do, the light is designed for a 55w bulb to have both lit simultaneously means you risk over hearing the wiring loom and the light unit it’s self.

I forgot to mention that I will not do this to my stock headlamps. To clarify, I'm considering to fit aftermarket Angel Eyes headlamps to my Grande Punto Abarth Esseesse. Something like these below:

I ask mainly because I've noticed that when these type of headlamps (they take H1 bulbs) are installed, when the full beam turns on, the dipped beam turns off instead of both be simultaneously lit together. Meaning, that they act the same way as the stock headlamp (takes H4 bulb) does. Here is an example:

What I mean by all this is that I want the full beams and dipped beams both be simultaneously lit together for my new aftermarket headlamps that I posted above...

These aftermarket headlamps take H1 bulbs, which means they have one bulb for the dipped beam, and another bulb for the full beams...

A simple diode between the two relay's coils will do the job...

Because I'm not familiar with this, is this just plug and play? What I mean by this is that in the future if I want to remove this, is it easy removable? Also, do you have a picture of this installation?

I'll keep that in mind

Your main and dipped beam are still very close together in a small space, you still risk too much heat in the head light unit damaging it, but yes it is possible.

If it’s that much of a problem you could always fit some auxiliary lights with powerful bulbs... for off road use obviously ?

Are you referring for my stock headlamps? If yes, I wasn't planning on doing this with my stock headlamps.

I will remove my stock headlamps and install aftermarket Angel Eyes headlamps (as I mentioned in this post: https://www.fiatforum.com/grande-pu...eams-dipped-beams-lit-together.html?p=4505892), and THEN I will do this dipped and high beam mod I was asking about

no, your after market head lamps will also not be designed to have both bulbs lit together. Incandescent bulbs in headlights generate a huge amount of heat. Just and increase in the wattage of one headlight bulb can be enough to start warping or melting plastic, where relays have stuck and the dipped beam not turned off with the main there have been times when the heat has basically wrecked the head lamps

I see... That's not good! Is it a better idea if I remove the high beam incandescent bulb and replace it with a good LED bulb?

Also, does an incandescent bulb get hotter than a Xenon bulb? I ask this because I already have a Xenon kit...

On the other hand, it makes me wonder, other cars that have H1 or H7 bulbs and turn both their bulbs on. Are their headlamps in the same risk as these too?

High powered LEDs get very hot as well which is why most of them have a heat sink and fan on the back of them. As for Xenon kits I have no idea how hot your set will get, you have to bear in mind they are basically an Arc lamp so likely to at least as hot as a normal bulb.

There is unlikely to be any significant benefit from having both in anyway as they light different areas in front of the car you won’t get lots more light in any one place. You’re better off looking at auxiliary lights you could hide in the grill if you want more light for very dark driving

Unless I find a LED system that is cooler? That's why ask for the 2 functions... I think I will figure out the LED solution...

Anyhow, is a simple diode between the two relay's coils all I have to do to get this done?

Despite having a projector for the dipped beams that will also be powered by Xenon lights? What are auxiliary lights?

Yes, the diode is all you have to do. You could also add a switch and you'd be able to disable this "option" ... There is no kit that I know, the diode should be installed between ports 29 and 30 of the fuse/relay box, anode @ 29 and cathode (mark) @ 30. The switch would be wired in serie with the diode. You'd get the same result if you install the diode at the other end, pins 10 & 16 of connector A, body computer module side.

Ok. How many A (or anything else measured) has the diode have to be?

One Amp will be way enough, 1N4001 is rated 50V, 1N4007 is rated 1000V ...

Ok. I can't wait to do this! Also, something very important, will the Grande Punto's ECU "permit" this kind of change? I mean, will there have to be a special "setting" or "configuration" done to the ECU? I ask this because then the load from the 2 bulbs simultaneously lit will be heavier than before...

Both circuits are sensed for open path/short to ground independantly, so the ECU shouldn't detect anything. Remember you have to "diode" the coils of the relays, NOT the outputs !

Yes yes, I will do that. I forgot to ask in my previous post, what happens with the car body computer/body control module? Will it allow me to do all that? I mean, once I do all the above you mentioned, will it be ok without displaying "error" or "burned out bulb/light" for example?

I ask all this because I don't know and also because the cars with body computers are very complicated...

The lights stalk is designed so you can't (mechanically) switch ON both relays, BUT when you make a "light call" (appel de phares in french) both relays are powered (if your dipped beam was already ON). In this case you got ALL ligths ON and the BCM doesn't complain, does it ?
BTW, you could also install the diode @ the stalk or @ the BCM !!
