Same for me, the bi-xenons on my old L322 were in a different class to the ones on my L405, one thing I really miss from the old RR. Steve

Fancied a light bar on my 405 so.... Here's the results

Looks great, how did you wire it in?

I have 2X 160W LED light bars I want to fit today. They come with very heavy gauge cable so I am a little concerned over how to wire them in without a controller or relay etc.

Wired it from a standard old school 4 pin relay sir...

There is a large (ish) battery cable in the loom near the drivers headlamp. Thats where i got the 12v+ from

I don't suppose you would mind doing some kind of guide?

I do have an automotive relay, did you wire it so the main beam triggers it? Or a separate switch inside the car etc.?

I see on Amazon they have the 433mhz remote looms, I was thinking to get this and then program it into my home link garage door opener to turn it on and off, only it states various modes including strobe lights (not fond of a mobile disco) Just a simple on and off is what I am looking for .

Thank you kindly

There are many guides of the net for wiring up relays sir. The only thing i added was a switch to the earth wire so i could turn it off when i didn't want it working every time i used full beam! Fog etc etc

Just to explain a little what a relay is/ does.
Most have 4 pins two of them are used for the low voltage draw from a new switch or an existing feed ie headlamp main beam, this side does not draw a large current so does not risk burning out the switch. The relay itself is an electronic switch so the other two terminals can then feed the appliance with current direct from the battery or a suitable fused supply. If you were to just wire a powerful set of lamps from a battery through a switch to the lamps you risk the switch overheating and causing a fire. 2012 tdv8 Westminster arrived Jan 19 gone Dec 23

NP. I am aware of that and have an extra wiring loom with relay, fuse, switch and deutsch quick connector to the lightbar. I will use the high beam shutter signal for relay control.

Craig mentioned an appropriate cable to use as power feed and it would save me a lot of time to get the direction to it and not having to trace the wiring diagram for hours. What I don’t want to do is to mistakenly connect to a 12V that is driven by an ECU output and cause a fault code or a destroyed ECU.

The best would be to find a direct connection to the battery as the lightbar circuit has its own fuse. I am reluctant to using the jump start points and am looking for another feed. And as this has been done several times by forum members I thought it would be a good idea to ask for help from the more experienced.

The safest way is to disconnect the plug fro your headlamp and meter out which pin supplies the high beam and use that as your trigger wire, then use the jump start post (underneath is a 13mm bolt head) for the battery + and next to the headlamp are several earth points sir… 👍

Ok, thanks Craig.

I had spotted as much but wanted to hear from you if there was another option as well. Then I am good to go, soon to be sorted.
