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.

As far as I know, all Grenadiers have the same very low powered Aux lights from the factory. The fuse/wiring to these lights is not capable of handling any significant light that you might upgrade to, including these Exzeit lights.

I find the off-road mode cumbersome and therefore do not recommend option #2 above.

I recommend wiring the relay power source directly from a 10A ceiling-mounted switch, if you have one available. Then use the high-beam wire (tap into that behind your headlight) to trigger the relay ON. That's my favorite setup.
