Auxiliary Lights in the Grill - High Power LED light upgrade without any cutting (now available on the Forum Store)

[Airleader]

I see a few ways you could wire these:

1) The lights come with a supplied relay.
2) You could use the existing lights power to energize the relay and wire new lights power to battery terminal in engine compartment. This would preserve the high beam function and utilize the off-road switch in cabin. EXT1 & 5 both still available.
3) Not use the relay in light kit and wire directly to EXT5. Off-road switch abandoned.
4) Use light kit relay and use EXT1 switch to activate relay and wire lights power to battery terminal in engine compartment. This would save EXT5 for future use and bypass the high beam requirement. Off-road switch would be abandoned.

Back to the electrics!

First a big thanks to the input here - it makes life easier!! I just got the ExZeit headlights and am still waiting for the mounting adapters. So it's time to take care of the wiring...
Maybe I overlooked it, but I'm missing point 5 in the list above:

5) Simply replace the original plug with the ExZeit plug.

I read somewhere that the original cables can't handle much current, but is there any way to quantify that? Do the EXZEIT auxiliary headlights require significantly more power than the original auxiliary headlights? In this case I would prefer 2) as I have the european wiring.
