Here is a run down on replacing the lights on your MQ & MK Patrol.
I found some replacement
Tail lights & Front Indicators on eBay, supposedly for the MQ/MK.
Apparently there are different types of plugs for the MQ/MK lights, as several eBay sellers state their lights suit both the MQ & MK Patrol. This is clearly not the case, as the light plugs on the MK, are different than other models. If you are looking for replacement lights for your MK Patrol, take note of what you are buying, because so far, I haven't been able to find replacement Tail lights and Indicators that plug straight into the MK Patrol harness.
This is the harness plug for my MK Patrol Front Indicator.
This is the Indicator itself showing the plug.
This is the Front Indicator sold on eBay as a replacement for the MQ/MK.
I have not seen an MQ or MK Patrol with the plugs such as the one above, as they are for the Nissan 720 models, but sellers state they fit. While they do actually fit as a replacement light, they will need to be rewired to suit your vehicle. I contacted a seller, and he spoke with his suppliers, who stated they both haven't seen a square plug like the one on my MK Patrol. While being excellent value for money, these Front Indicators clearly aren't a "bolt in replacement" for the MQ/MK Patrol as advertised by various eBay sellers.
This is the Tail light sold on eBay as a replacement for the MQ/MK Patrol.
It has the same plug as above, and will also need to be rewired to suit your vehicle.
The MK Patrol has its Rear Indicators located in the bumper, and rewiring it will be a bit harder.
You can rewire this MK Tail light, and take the Indicator from the bumper to this Tail light, or you
can rewire it so you tap into the Indicator from the bumper, and utilize them both as Indicators.
Below is a guide to the layout of the Tail lights for the MQ/MK Patrol.
