It should come with instructions.
It needs to be an approved tow ball.

do not drill any holes into the towbar or it will not be type approved.

not going to as i remember u saying not to drill any holes as I was going to fix some lights

going to put my roof rail on and mount some lights onto the back bar of the rail

still trying to find out what the data on the badge mean

first line is the approval

50 I assume is the ball diameter

looks like the s means 250 kg ,as nose weight ??

still working on the d bit, lol

The "D" value is calculated as follows:
(GVW x GTW ) / (GVW + GTW) x 9.81/1000 (gravity)= kn
Where GVW is Gross Vehicle Weight, and GTW Gross Trailer Weight.
The maximum D value for an M1 vehicle is 17.7kn that represents a GVW of 3500 kgs towing GTW of 3500kgs.
It is possible to design a towbar that fits the whole range of models of one particular vehicle. Because Towing Capacity is related to GVM then each model may have a different value for D. To prevent overload of the Towing Vehicle refer to the Vehicle Manufacturers' Handbook to confirm the GTW for your particular model.

Thanks Hippo. I've been hiding in the bushes watching for a while! Picked up some pretty decent knowledge from here and various groups on Facebook. Should help me keep my 05 plate td4 HSE going!
