Just browsing EBay and came across these

Says they will fit the j

Says a 12v ignition feed I know there was a problem with these on the insignia I think it was (catch fire) so was thinking a switch could be used so they are only on when you need them on.

Does anyone know if these can be changed for the old type that you could adjust with a pin?

Reason is the drivers side always shoots over the car tried adjusting it I can't get any lower, I've also damaged it trying now.
