Ive just done the same "swapped out my LED stop/tail bulbs for a proper LED unit from BoltOnBits"
Loads better. I'm not going to bother with indicator but may do the side lights.
Just bolted mine down in the right place with no sliders. Mine has a small steering wheel so your legs don't hit.
Passanger box has an anderson connection on the front for jump leads. That way you don't need to get to the battery but don't take long if you need to.
Collecting brownie points to spend in the next 6 months ;)
My list;
Decking (Done)
Change carpet in bedroom(1/2 done)
Combi boiler
Multi fuel burner
Pitched roof on the porch
& maybe bathroom.
My words of advise as I've had both.
Don't buy a Disco cos you'll be spending all your time welding it up & repairing it.
With a Defender you'll only need to repair it. :laugh:
