They are still just LED's without any built in control so yes you still need either a resistor or change the flasher unit but if you retain conventional bulbs in the front indicators you usually get away without having to do it. If you change both ends you will have to address it.
As you can see ive been busy with a few mod's..
Canopy was built by Kylin campers and big mouth scoop came from Mr Bodykits (ebay)..drawers are 900mm Kings and the fridge slide come from MSA and table from Clearview.
I originally wanted to fit an MSA drop slide but was unable to because the mounting position wouldnt allow it to open without hitting ute so I Purchased an ironman glow in the dark (I sholt you not) step to make fridge access easy..
The spare wheel holder also come from Kylin and is adjustable to suit all wheel and tyre combinations.
Next will be an awning when I can decide what breed to get.
